research themselves, mainly focused on developing new psychic powers. Illithids regularly conduct raids on all sentient settlements to acquire new thralls, because their existing stock of sentient thralls do not breed fast enough to satisfy their food and labor needs. Typically, a group of mind flayers will teleport to the settlement and swiftly incapacitate them with their psychic powers. The captives will then be marched all the way to the illithids' underground settlement by specially trained and conditioned thralls. Great care is taken to cover their tracks. In various campaign settings In Dragonlance The yaggol are a variant presented in the Dragonlance campaign setting.

In Greyhawk Illithids typically dwell in dim, underground settlements, usually in the Underdark. Perhaps the best-known illithid settlement on Oerth is the city of Dra-Mur-Shou, located within several miles of the Vault of the Drow. A number of illithids also make their home in
