Mass Effect: Circle of Ashes

[Sirrocco]

Actually, I can see it as a sort of odd almost Space Amish thing - there are those who follow the Old Code and avoid all taint of the Cursed Tech, and are mostly marginalized off by themselves in tiny systems that people let the have because it's not worth taking them, mostly trading with one another because they can't really compete with the rest of the galaxy. Then the Reavers show up and suddenly everyone except for this strange, insular, backward, cult-like group following an ancient doomsday prophecy is dead. That could wind up being a very interesting little story in a number of ways.
