Simon Atwell

Simon Atwell is the chief engineer on Asteroid X57. He was originally in charge of bringing X57 across the system to Terra Nova, where Simon lives with his family and grandchildren. Unusually in the galactic community, Simon likes and respects quarian workers, having hired quarian specialists in the past for mining jobs. When the asteroid is attacked by batarian extremists, Simon manages to escape them and hide on X57's surface, to eavesdrop on the batarians. He later sneaks into one of the fusion torch stations, presumably to try and shut it off, but only succeeds in shooting Commander Shepard by accident.

Simon is then able to give Shepard background on the situation - painting a dire picture of what happens if X57 hits Terra Nova - the name of the batarians' leader, and a warning about blasting caps around one of the fusion torches. Simon is also concerned about three missing engineers and Kate Bowman. Shepard tells Simon to find a safe place to hide.

After Balak is dealt with, Simon reappears, having returned to the main facility to lend a hand if he could. Shepard can justify the decision to kill Balak or let him go, and Simon explains Shepard's actions have saved Terra Nova. He offers equipment as a reward. Shepard can pick from light, medium or heavy Colossus Armor, a rare set of quarian armor (left behind by Simon's former quarian colleagues) or a nice omni-tool.
