Mind flayer

The Illithids, commonly known as Mind Flayers, are creatures found in the Underdark.

Creature Information
Illithids are characterized by there lengthy height, purplish skin, facial tentacles which surround a toothy maw, and levitation ability which is often used for movement. The Illithid are connected by a central "brain" known as the Elderbrain that allows them to share experiences communally. Mind flayers are suspicious of the arcane and practice of such can lead to expulsion from their society. They are considered evil.

Illithid that have been banished from their colony seem to go insane, and long to return to their hive.

Vox Machina encountered several mind flayers during their travels in the Underdark. They also infultrated a Mind Flayer city called Yog Voriel and nearly destroyed the Elderbrain residing within.

Abilities
