Early LifeEdit

Friends with Marcus FenixEdit

Dom was born to Eduardo and Eva Santiago in Tyrus during the 60th year of the Pendulum Wars, and lived in the city of Ephyra with them and his elder brother Carlos, and attended Olafson Intermediate School. When Dom was eight years old, Carlos met and became friends with Marcus Fenix, and Dom became friends with him as well. When Dom was eleven, Marcus came over one day to spend the day with the Santiago's, and he helped his mom set the table while Carlos, Marcus, and his dad worked on a car engine. Eva asked him what Marcus' parents were like, and Dom told her that they were nice, but seemed to treat him more distantly than she and Eduardo did. She told Dom that he was very observant about people, and that she was proud of him and Carlos for being there as friends for Marcus. When they finished setting the table, Dom went out to help work on the engine, but also kept looking over the fence into a tree in their neighbors’ backyard, where a girl named Maria had just moved in with her family and often climbed the tree. Dom was interested in her, and had been trying to gather the courage to speak with her. After working on the car engine with the others for a while, the Santiago’s and Marcus began eating, and Dom listened as his dad talked about being in the army with Carlos and Marcus, and Dom was alarmed and worried about them possibly joining the army in several years. The dinner was interrupted when the phone rang, and Eva told Marcus that his father had called. Dom learned that Marcus' mom had gone missing, and Marcus' father came to pick him up. Dom and Carlos were worried about him, and he didn't show up to school for a day. When he did show up, the three of them talked after school, and Marcus told them that he didn't think his mom was coming back, and that his father was not telling him everything about her disappearance. This led a rift between Marcus and his dad, and he began spending more time with Dom and his family, and Dom and Carlos considered Marcus to be another brother.

Marriage to MariaEdit

Five years later, Dom had begun dating Maria, but accidently got her pregnant. They decided to tell their parents and get married, even though they were young and still in school. Dom told his father, who was understanding of his decision and proud of him for accepting responsibility. Dom was glad for his father's support, and after he told him mom, the two of them went to the Flores' house, where Dom and Maria told her parents while Ed stood back to offer them support. Mrs. Flores began crying, but Mr. Flores told Dom that he had guts for coming and telling them, and that they better get married. As they left, Dom swore to himself that this was the last stupid thing he would ever do, and would finish his schooling and get himself a good job to support his family. He also decided that Carlos, who had recently joined the army, would be his best man, and decided to learn from his example on how to do things. Several months later, Dom and Maria got married, and Marcus had joined the army as well. Dom and Maria talked about their options, and he decided to drop out of school and join the army as well in order to support Maria and the baby. After the wedding ceremony, Dom told Carlos about his decision, which worried Carlos, but he acknowledged that it had only been a matter of time before Dom did join up. At the beginning of Frost, Maria gave birth to a boy, and they named him Benedicto Santiago. By Thaw, Dom dropped out of school and joined the army.

Early Pendulum WarsEdit

Dom joined the experimental commando units with his trainee partner Georg Timiou. Dom passed his commando training and was subsequently part of Hoffman's commando team to take part in Operation Leveler. The day before the Battle of Aspho Fields, Dom's second child was born, Sylvia Santiago. Dom took part in Op.Leveler and was able to save many of the Commandos at Aspho Point and was awarded the Embry Star. After Aspho Fields, he stayed home to be with Maria and his kids. They stayed in their Lower Jacinto apartment for a couple more years until they got enough money to rent a house back in Ephrya City.

End of the WarEdit

Skirmish in Ghato CityEdit

Two years after Operation Leveler, Dom had become part of C Company and was part of a squad that consisted of Marcus, Pvt.Padrick Salton, and Pvt.Tai Kaliso. He and the rest of C Company were sent to the Independent Republic of Furlin, and dispatched by their commander to Ghato City. They encountered a small Indie force in the ruined city, and became pinned down by them in a collapsed building. Marcus ordered Pad to get on a roof and snipe the Indie heavy weapons users, while Dom, Marcus, and Tai provided covering fire. As Pad ran for a roof and they fired, Dom asked Marcus to remind him how much ground the COG had gained that week, and Marcus guessed that it was zero again, which is what Dom had thought. Pad sniped the Indie heavy machine gunner, and Dom and Tai followed Marcus as he led a charge on the Indie position, with Pad sniping two more Indies, leaving only three left. They overwhelmed the Indies with fire and cut them down, and Marcus reported to control that Ghato was secured and they would meet up with the rest of the unit in Tenla. As they walked along the side of the road out of Ghato City, Dom remarked that he had thought that the war would have been over in months after the raid on Aspho Point, and that he sometimes thought Carlos had died for nothing. Marcus told him not to think that way, and that his father said that the data they had retrieved had cut years off of his work. Dom asked him if Adam had ever discussed it with him, and Marcus told him that for his dad, top secret meant top secret.

Ceasefire and AmbushEdit

Two weeks later, C Company was travelling along a cliff road that overlooked a small Furlin town. Dom was glad to see someplace that hadn't been bombed, but Marcus told him not to tempt fate. The convoy then stopped, and Dom and the rest of the squad were called over by some other Gears. They listened with the rest of C Company as it was announced by Chairman Tomas Dalyell that the war was ending with the UIR's surrende] after the deployment of the Hammer of Dawn orbital weapons platforms, which had been designed by Adam. Dom and the other Gears began celebrating, but were stopped and shocked when they were shelled by an Indie unit in the mountains. Several vehicles were hit and some shots hit the town below, and Dom remarked that this was insane and that someone needed to tell the Indies they had surrendered. Marcus reminded him that they technically hadn't yet, and they joined in with the rest of C Company in opening fire on the Indies while their commander tried to get the Indies to surrender. Several mortar shells hit near Dom and the others, and he saw Novak go down. Dom began cursing in frustration, saying that no one should be dying now since the war was over. A few moments later, the Indies did stop firing, having received word from their superiors that the surrender was real and not a COG trick. Dom was relieved, but disappointed looked down at the town below them, which had been heavily damaged during the shelling. Three hours later, Marcus showed Dom the Indies coming down from the mountains and surrendering, and told him that it hadn't all been in vain. The next day, C Company had moved into the town, and Dom waited silently with Marcus and the rest of the squad as noon approached, at which time the surrender would go into full effect and end the Pendulum Wars.

Emergence DayEdit

After the end of the Pendulum Wars, Dom and Maria rented their first house. One day, Maria sent the kids to her mother's so they can have a day to themselves (this day was in Dom's dream in his flashback dream after being swallowed from the Riftworm). Unfortunately, this day was Emergence Day. On that day, Maria's parents were killed along with Benedicto and Sylvia. Both Dom and Maria where able to evacuate back to their house in Jacinto while the Locust attacked the city. However, Maria was pushed over the edge of major depression with the loss of her children, her new life destroyed, and Dom's constant presence on the front line.

One year after E-Day, Dom and Maria continued to live their lives; Dom spent much of his time fighting the Locust, while Maria was prescribed with anti-depressants and stayed at home. She sobbed about her children and would still clean their rooms and go out for walks believing the kids are still alive. Even during the Hammer Strike she wanted to go out. She blocked out the truth about her children, and Dom became upset with her denial. One day, he didn't find her at the house: Adam Fenix had her escorted to the Fenix Estate for her own safety a couple of days before the planned Hammer Strike on Sera.

Four years after E-Day, after the years of grief and depression, Maria left Jacinto and vanished, devastating Dom. This, along with the loss of his parents and children on E-Day, makes the war with Locust deeply personal.

About ten years after E-Day, Dom testified in Marcus's favor during his trial, when Marcus was charged for Dereliction of Duty in the face of danger, and was sentenced to death. Dom saved his friend from execution by testifying that day, but Marcus Fenix still went to the[Jacinto Maximum Security Prison (the Slab). As a result of his testimony, Dom lost the trust of many people, and cost him the chance of being promoted by his superiors because they believed he had more loyalty to Marcus than to the COG, even though many respected him for not abandoning his friend.

Lightmass OffensiveEdit

After Col.Hoffman pardoned all the inmates from the Slab except for Marcus Fenix, Dom rescued him when the Locust took over Jacinto Maximum Security Prison, and he helps him escape the jail. Afterwards, Marcus and Dom joined Delta Squad. They are ordered to retrieve the Sonic Resonator to deploy in the Locust tunnels. They fight through several parts of Ephyra, rescuing the remnants of Alpha Squad (who originally possessed the Resonator) and narrowly survive a brutal Berserker ambush. Marcus is promoted to sergeant when Lieutenant Kim dies at RAAM's hand, and Dom then offers his assistance in leading the team to Franklin's Outpost.

Upon arriving at the Stranded outpost, Dom calls in a favour he is owed in order to borrow a Junker called Laverne from Franklin. The Laverne would be used to safely transport Delta Squad to the Lethia Imulsion Facility, where they would deploy the Resonator. Marcus and Dom must leave Cole and Baird behind as added defense for the local Stranded while Dom and Marcus secure the Junker from Chap's Gas Station. They form Delta One, and fight through several waves of attacking Locust, all the while sustaining attacks from the vicious Kryll. They eventually reach the station, and begin to fuel the Junker. When Locust forces attack the Gas Station, they narrowly escape back to outpost to pick up Delta Two. After one last massive firefight at the HQ, the combined team finally heads for Lethia Imulsion Facility.

The entrance to the factory is blocked, and the team must once again split into their two teams. Upon discovering an entrance, Marcus and Dom travel through the Lambent Wretch infested facility, and head into the underground caverns. After facing many Locust, including a Corpser and several elite Locust known as Theron Guards, they successfully deploy the Resonator, and escape The Hollow in the nick of time. With the Resonator activated, their mission was complete.

However, soon after the team makes it outside, they learn that the Resonator has failed. Upon discovering a geobot with massive tunnel data, however, they find that the focal point of the data is Marcus's old house. Dom and the rest of Delta Squad are picked up by King Ravens and transported to East Barricade Academy, the site of Marcus's old home. The team splits up once more, as Cole and Baird stay behind at the Contemporary Fighting Center in order to tend to wounded Gears, so Marcus and Dom go on ahead. After fighting through the defensive posts of many Locust that infested the campus, Dom and Marcus finally reach the house. Delta Two is able to link up, but quickly departs to repair an APC in the back of the house. Once inside, they gather all the information needed and barely escape a massive Brumak onboard the APC.

Delta Squad hurries to Timgad Station where the train which carries the Lightmass Bomb will soon pass through. Dom and Marcus board the train, but Baird and Cole reach the train too late. Separated, Delta Two radios that they will wait for King Ravens to pick them up. Delta One receives intel saying that the bomb is at the front of the train and that they must start heading there now. As the lone pair heads to the front of the train in order to activate the bomb, they are confronted with yet another Berserker, Locust Reavers, and Lambent Wretches. At the front of the train, they encounter General RAAM guarding the Lightmass Bomb. Dom lays down suppressing fire, while a King Raven provides air support and Marcus takes pot shots at the general. Marcus loads the targeting data and deploys the Lightmass Bomb into the tunnels, narrowly escaping as the bomb detonates. The bomb annihilates multitudes of Locust, scoring a much-needed victory for the humans. Dom jumps onto the King Raven and is just barely able to pull Marcus onboard, with the help of Colonel Hoffman.

Sinking of Tollen and MontevadoEdit

Dom, along with Delta-One, took part in the Evacuation of North Gate. Dom met Bernadette Mataki during the Ambush at Sovereigns Boulevard. She joined Delta and took part in the evac of North Gate Agricultural Depot, getting all the supplies out of the deport. She later told him about the death of Carlos and he showed her the pictures of his children. Some time after the evac Dom took part in the Mission to the Pirnah Badlands, on a search and rescue mission for missing gears. The mission was a failure, and afterwards Delta had a week to leave. Dom, however, couldn't stand staying one week in Jacinto knowing Maria was out there. He was more then eager to get back to the field. On the Mission to Montevado]], Dom and the rest of Delta were shot down over Locust territory. Dom and Delta made it to Montevado on foot, but as soon they entered the city it was sunk by the Riftworm. Barley surviving the sinking, Delta was attacked by Bloodmounts in the sinkhole. Dom was ordered by Marcus to escape with Jace Stratton. All the members of Delta except for Michael Barrick made it out of Montevado. In the month after Montevado in a Battle near Jacinto, Dom remembered what he was fighting for and hoped one day he could have Maria back.


Dom along with the rest of Delta with members from Sigma-One and Foxtrot, were sent to the city of Jilane. After a distress call, they traveled to the old birthing farms there. Dom hoping to find Maria there but was told by Alex she was better off somewhere else, decided that the city was the best shot to find her. After entering the city Delta was split into two groups, Jace, Cole and him set off looking for any survivors. Only to find dead fetuses and evidence of a massacre. While Fenix, Alex and Baird came under attack from the Jilane survivors.

Operation Hollow StormEdit

Six months after the Lightmass Offensive, the Siege of Jacinto is tightening. Dom was getting conflicting reports on Maria, including a sighting at Jacinto Med. Not finding her at the Hospital, Dom felt he had lost her again. Dom, along with Marcus and Benjamin Carmine, took part in Op.Hollow Storm and fought their way to Landown. After entering the Hollow, Delta fought their way though various Locust hardpoints and eventually ended up in the newly sunk Ilima sinkhole, finding Cole and Baird on the way. During extraction, the King Raven they are on was swallowed by the Riftworm. After cutting the arteries around the Riftworm's three hearts and killing it, Delta cut their way out. However despite requesting pickup they are dispatched to investigate the New Hope Research Facility.

At the facility, Dom and Marcus reconned the buildings. There they discovered the Sires and clues that led them to Mount Kadar, where they reentered the Hollow. Upon finding a small ground of Stranded, Dom also discovered Maria's location. Dom immediately set off to rescue his wife. Marcus initially objects to this, wanting to continue on with their mission but Dom convinces him to help after reminding him he did the exact same thing for his father. Dom and Marcus infiltrate the camp and eventually find the pod that contains Maria. Upon opening the pod, Dom, apparently delusional, sees his wife in perfect health. However, he quickly recovers from this and comes to see Maria is malnourished, scarred and has been mentally broken from the torture of the work camps and the deaths of her two children. Dom desperately tries to remind Maria who he is but all she can do is gaze emptily at him, showing absolutely no recognition of who Dom is. Devastated, Dom decides to euthanize her, telling Maria how sorry he is that he couldn't find her in time and how much he loves her. Marcus walks away, and in the distance he hears a gunshot; Dom later appears and Marcus apologizes for his loss. Dom and Marcus continued to infiltrate Nexus, the Locust capital, again meeting Cole and Baird on the way. After killing the Locust high priest Skorge, but failing to kill the queen, they return to Jacinto. There, they discover that in order to place a Lightmass bomb that will sink Jacinto but flood the Hollow with water, they must return underground. After hijacking a Brumak and using it to clear Locust from the area, Jacinto sunk and the Hollow flooded. Flying away from the ruins of the last bastion of humanity, Dom is left to an ambiguous future.

The fall of Jacinto and living without MariaEdit

In memorial of his wife, Dominic had his "Maria" tattoo reworked to add an angel. He also has grown a beard and accepts death without a thought. When the COG disbanded after The Lambent Surfaced, he joined Delta on the CNV Sovereign.
