Author has written 3 stories for Mass Effect.
Current projects (Updated 30 June 2016):
Chaos Effect: First Contact. As the name sort of suggests, it's the first part of Mass Effect universe 'fan-fiction'. Apart from the galaxy, races, and a bit of technology, it's all original story and characters. Story finished.
Chaos Effect: Dawning. Sort of a transition between CE:FC and CE2:R, CE:D is a better look at the backstories of various original characters. Set before and after CE:FC, it's finished for the time being. No plans to add more in the foreseeable future.
Chaos Effect 2: Revivification: The chronological sequel to First Contact. Set in 2190, past the events of Mass Effect 1-3, but slightly AU. Like CE:FC, it's almost entirely OC driven. Needs to finished. Desperately.
