This LJ is part of the vorkosiverse RPG, and this character is played by quietann who is in Massachusetts, US. All characters belong to Lois McMaster Bujold, but what we do to them here is absolutely Not Her Fault. :-)
Gregor is in his early 40s and has been Emperor of Barrayar (and its associated planets Komarr and Sergyar) since he was 5 years old. He is married to Empress laisa_v and they have two young children, Crown Prince Xav and Princess Kareen.
