Magic: The Gathering PnP
Lazav is the guildmaster of House Dimir. After Szadek was killed and gained control over Agyrem, Lazav managed to gather what was left of the Dimir and bring them together. A ritual was supposed to allow him to commune with the previous guildmaster’s spirit, however it is unknown whether that was true or just a ruse. Since the Dimir guildhall was lost to all, he built a new Duskmantle, which replaced the old structure.
Lazac continues to use most of Szadek’s methods, giving both his own agents and mercenaries (one of whom is Krenko1) as little information as is required to further his goals.
Details from himself are unknown, including Lazav’s real gender. He claims that he takes orders from some greater power.
