I made Mgt as a character for his SG so that there would be someone else earning prestige for it. Eventually Ted seemed to get burned out, with all the play time, the beautiful base he was always improving and no one saw, and his story arc no one played. It happens. He'd show up occasionally after that, but even those times he didn't feel like teaming.
Then one day he completely disappeared. Those of us who had been in his SG were booted out, and his MA arc was gone. We never heard from him again. Whatever led him to that I'm sure wasn't pleasant. I wish him well whatever he's up to.
Anyway, about Mgt. The name is from a series of books, The Illuminatus! Trilogy. Mgt is a character that keeps posting odd instructions, always signed "The Mgt". People presume it is the "management" who posted them, when it was in fact "the midget", an agent of chaos. So yes, it was always my intent to turn my Mgt into a rogue, but he just never got there.
He transferred from Infinity after "Ted" had imploded. It was a sad thing, and I didn't feel like playing him much after that. (Technically, his name on Freedom was "Mgt1"; the pure name was not available there.)
