The offspring of a yuan-ti abomination and a marilith demon, the creature known as the Serpent Sibyl is a thing of terror. She looks like a large serpent, about 14 feet long, with thick black scales and glowing red eyes. Four humanoid arms, also covered in scales, protrude from her body below her neck. She uses two for spellcasting, while two wield her massive spiked chain. Two great wings, like the wings of a pterodactyl, stretch from her back near her arms.

The Serpent Sibyl believes herself to be a reincarnation of Sseth, the avatar of Set who ruled Serpentes a thousand years ago. Her followers believe so, too. She is coldly arrogant, cruel, and despotic, but she has the ability to inspire her followers -- stirring them with visions of the grandeur of their ancient empires, spurring them on to regain that lost glory. She herself believes wholeheartedly in that vision, and imagines herself ruling a new, grander yuan-ti empire for centuries, just as Sseth did.
