Andrei
From the journal Coen keeps.
From Coen's journal
Brencis may be the knyaz of Vale Sangora, but when it comes to Svartrau's underworld, he has serious competition. The gambling, black market and brothels are run by a certain Andrei. He's a secretive man – even those who work for him know little about his origins. He can sometimes be found near the Eastern Gate, by the butcher's shop – which seems fitting for a man of his reputation.
