The [O21] Illithids Race Mod is a Forgotten Realms based mod adding the Illithid race, also known as Mind Flayers.

[O21] Illithids Race Mod features

  • New Race: Illithids
  • Start scenario with an Elder Brain Jar, an item required for building the new Elder Brain structure.
  • The Elder Brain structure passively builds up a few Illithid tadpoles which can be extracted for use in a new surgery option, this will convert any pawn into an Illithid through ceramosis, a process in which the tadpole replaces the brain of the host and transforms them into an Illithid. I’ve said Illithid too much.
