So my idea right now: a female drell named Cyn is the hero. She goes to the Citadel with a new hanar ambassador. She’s his bodyguard. They arrive at the station and she’s immediately arrested by a turian C-SEC agent.
The first option will be to accept the arrest or resist.
Now I just need to work my way through all the options until the end. Ah, and also figure out the end :D
