(*) After the End: Shepard's choice was not as lethal as they had first believed. After the explosion that claimed much of synthetic life in the galaxy, the Citadel was scoured from top to bottom, an effort that was taking months upon months. However, the commander was never found. A valuable price, they were extracted from the debris by surviving Batarian slavers who had gotten to the scene first. Shepard was still widely hated by the violent race, due to his frequent actions against them, and the boss of the slavers had a vested interest in having Shepard brought before him, for he knew of the commander's hand in destroying a Batarian system, in which his entire family had been living. Taken to the slaver lair deep in the Terminus Systems, Shepard isn't a captive for very long. After a single torture session, they are sprung by a familiar (or unfamiliar) face. Having heard of what had happened to the commander, and not finding any ears willing to listen, the individual single-handedly spent a lot of time and effort in tracking them down. Now, the two need to stop the slaver's operation and get off the rock in one piece. Maybe then, life can return to a semblance of normal.
(*) The Skyllian Blitz: The Skyllian Blitz was a defining moment not only in the career of Shepard, but also many other men and women who gave their all in the defense of Elysium, a small human colony in the Skyllian Verge. The initial ground assault was terrible, with civilian casualties skyrocketing due to the excessive force applied by the invaders. Working closely with Shepard throughout the days of the Blitz was a young, female soldier. It is their mission to hold out for reinforcements come, while making hard choices concerning which population centers to back up, and which to let burn...
Always in Trouble: Deacon has gotten himself into a significant bout of trouble. After taking on a mission that seemed routine, it turned out to be little more than a hoax to draw him out into the open. Double-crossed on arrival, he barely makes it out alive, and is left with no means to leave the area. Stranded, he realizes he needs a special set of skills to make it out alive. This is where your character comes in. Depending on what works best, either old or new enemies, or Cerberus, has made Deacon their target. Either on a desolate, or a densely populated planet, they are hunting him down and he needs something that your character is good at to get off again. He approaches them with an offer and hopes they will consider helping. To tie things together better, we can plan it so your character has a vested interest in getting off the planet as well, or to stop whoever is hunting Deacon.
Cut Off: The destruction of the Reapers caused widespread chaos in the galaxy. Governments were struggling to get back up on their feet, and with the Mass Relay network down, countless colonies are left with nowhere to turn for supplies or protection. One such a colony, a distant one owned by a now-defunct corporation, sports a sizable population of all manner of races. However, incompetent management, stress, fear and a lack of contact with the outside is stirring up trouble and the more outspoken elements are becoming restless. Not much will be required to cause riots and even violence to flare. When a storm hits the colony and blankets it entirely, a coup is staged to try and "fix" the incompetent, though innocent, manager's mistakes. A lot of innocents are dying in the crossfire, and it is up to our two characters to set things right. Deacon will have arrived at the colony shortly before the storm, part of a supply run funded by the Systems alliance to help isolated colonies. Your character's activity or the reason for their presence, is yours to decide on.
(*) Rannoch Terrorized: [Tali'Zorah] After the defeat of the Reapers, the Quarians can begin their reconstruction of Rannoch. However, it seems that the custody of the Geth was not as perfect as they had once claimed. While the cities were maintained, the wildlife outside was left unchecked. Now, with the Geth protection gone, Rannoch has quickly become the target of slavers, smugglers and other unsavory elements. When one crime lord proves to be a far greater challenge than expected, and his terrorist activities cost a great many lives, Tali'Zorah is ordered to call in favors wherever she may find them. She knows of only one person who drop everything to come help her people...
(*) The Geth Solution: [Tali'Zorah] The Quarian plight to reclaim their homeworld from the Geth is well-known, but the actual battle is a very personal one. Often shunned and watched on Council Worlds, all the race wants it to get their old home back, or find a new one. Few are as passionate about this fight than Tali'Zorah, and after the defeat of the Collectors, her journey began taking her far and wide. Every useful information that might hold a clue to stopping the Geth without the need for a costly war, was important; important enough to outsource. When what she needs is being held on a moon in the Terminus Systems, and she finds no help coming from home, she turns to Deacon, who was still grounded on Earth. Willing to do anything for her, he manages to break free of his custody and puts everything on the line to give her a home.
The Illusive Hunt: [Miranda Lawson] After Miranda leaves the service of Cerberus, she ends up on the same list as all enemies of the shadowy organization do. Despite having to dodge assassins and operatives constantly, she keeps herself alive, and her family safe. However, stopping Cerberus becomes a priority when her sister disappears. However, Shepard is more than willing to help someone he owes his life to. A lull in the fight against the Reapers, caused by a complete lack of leads, gives him all the time he needs to help Miranda bring Cerberus down.
(*) The Dark Colony: [Ashley Williams] Life became exponentially busier for both Deacon and Ashley when the Reapers were defeated. The entire known galaxy was in disarray and the destruction of the mass relays and significant amounts of technology, only made matters worse. Many colonies got cut off from their governments, if a government even still existed, and became the ideal prey for pirates, slavers and other unsavory elements. Still serving as a Spectre, despite the disorganization rampant on the Citadel Council, Ashley was ordered to travel to a remote Turian colony, with which all contact was only recently lost; after the destruction of the Reapers. Foul play is suspected and when she arrives, she finds signs of battle. After scouting for survivors, she finds a familiar face, Deacon, who had been investigating the same incident for the Systems Alliance, solo and covert. Together, they decide to get to the bottom of it. Perhaps the Terminus Systems are taking advantage of the situation, or perhaps it is something far more sinister.
Struggling to Survive: [Karin Chakwas] During his struggles against Saren, Collectors and Reapers, wounds were frequent. But, Dr. Karin Chakwas was always there to patch him back up, with a smile. After Deacon's fateful decision to destroy the Reapers leaves him on the brink of death, there is only one doctor he would trust his life to. The rehabilitation is lengthy, but it's time he can spent with a woman who means more to him than she knows.
The Mastermind: [Maya Brooks] Deacon's crusade against the remnants of Cerberus has not been proceeding well. Many of his attempts at thwarting their distant activities and reconstruction efforts have ended in failure, simply because they have become too fragmented to track down properly. Still incarcerated for her crimes, Maya Brooks - although that is not her real name - gives Deacon an offer he finds he cannot refuse. In exchange for being allowed to come along, she will help him find her former associates. Of course, she has an agenda of her own, but who knows what that might be? Given no other option, Deacon accepts.
Living on the Edge: [Jack] Jack's life felt empty after the end of the Reaper War. A lot of her students had lost their lives, and there was precious little work for her as long as rebuilding efforts continued. But, there was one shadow of her past that simply refused to die. While weakened to being a mere fraction of what they used to be, Cerberus still lived through the machinations of a single man. Leading the remnants of the organization, he was trying to eek out a comfortable home in the fringe of the galaxy. Sharing her aspirations to see them undone, Deacon offered to help her put an end to Cerberus, once and for all. The ringleader was a survivor of the project that tortured Jack since a tender age, as well as committed such atrocities as murdering admiral Kahoku and attempting to have Shepard's mother assassinated. It was personal for both of them.
