Staring Dark, Troll Ranger 5/Rogue 3/Assassin 2/Blackguard 5/Oozemaster 5. His favored enemies are Aberrations and Humanoids (humans). His oozy touches are Gray Ooze, Phosphorescent fungus, and Green Slime.
He's much more intelligent than most of his race from Illithid experiments-- and from eating their brains in payback for having been experimented on. As part of their experiments, his skeleton is a slotless magic item that duplicates an Amulet of Natural Attacks (+5 keen charged, and his natural attacks are modified as a weapon made of adamantine) and gives him DR 2/-.
His break into the Oozemaster class came from Curse of the Azure Bonds, when he was engulfed by a Bit o' Moander and ate his way free of it.
He hates the Red Wizards with a passion, and hates most Wizards with a casual disdain. Despite his evil nature, he hates slavery and will destroy it wherever he finds it. He's not too picky about keeping the slaves alive, however. He hates Illithids. He hates Drow.
He had a part in destroying Vecna in Die, Vecna, Die. He assassinated King Azoun. He's entangled up to his eyeballs in Abyssal and Infernal politics, but he's managed to avoid several assassination attempts.
