Dark Lord: The Complete Council

From publisher blurb:

Complete your Dark Council with the six sinister dark lords contained within these pages! Lead the horned hordes of the Beast Lord, master the subtle poisons of the Dark Elf Matriarch, embrace the bizarre power of the Elder Brain, become one with the swarm of the Hive Queen, mesmerize your foes as the cunning Naga Empress, or drag them down into the primordial depths as the Sahuagin High Priestess!

Note: This is an expansion book, Dark Lord: Lords and Minions is required to play. All six of these new dark lords are in Dark Lord: Ultimate - if you already have that book, you don't need this one.
