Bach is a Prime Imp of the Royal variety, though his bloodline is far enough removed from the throne as to not be listed on the Royal Genealogical Veins. From a fairly young age, he was a guard, and signed up for MEER when it was reestablished following the failed coup of Leda, Mother of Grifters. His career there was not terribly long; a handful of trips into Universes 8 and 9 without incident, followed by two ventures into Universe 1, where he lost his right arm and leg. His arm was replaced with machinery found in an amusement park by a wizard of Universe 8, while his leg was replaced by a professional (and Talynted) cyberneticist.
Due in large part to the poor function of his mechanical hand, MEER made up a job for him, Gnostimancer, knowledge diviner. In truth, he is but a receptionist, whose job is to log new data and dig up the old. He has made his own work by creating an internal computer archive of MEER knowledge and exploits, in addition to being a rare friendly face at MEER headquarters. His computer tech is taken mostly from Universes 4 and 1, with some primametan magic in the works.
