In the Darkest places

(Venom/Mass Effect 2 & 3 Crossover)

A Cerberus team finds an asteroid floating through space and finds millions of Sybiotes. Three years later, The Illusive Man has Shepard track down a rouge 'specimen' to add to the team. He finds the specimen named Mayhem who is bonded to a female Quarian who was on her Pilgrimage when she stumbled upon the silver Symbiote. He persuades Mayhem to come onto the ship and after a small chat Mayhem finds a nice quiet, damp, dark area to stay.

(Disclaimer: I do not own Symbiotes, Marvel does. I do not own Any Mass Effect characters or plots, Bioware does. I only own my crossover idea.)
