Illithid Tadpole

Found in fossilised form in a chest beneath Vester Keep. It was researched by Vyodros. Chipping away at the encrusted rock, studying the anatomy, Vyodros was able to deduce that the tadpole has potent transmutation abilities able to inhabit a humanoid being for a long periods of times, granting them psionic abilities before being turned in a mindflayer during a transition period known as ceremorphosis.
Upon its awakening, the creature attempted to inhabit Vyodors, but he was able to pull the creature away before it made its escape. Tearing through the floorboards of the guildhall, Vyodros was able to capture to the tadpole before it could find a new host to enslave.
