Ch'Chitl

Ch'Chitl was a city of mind flayers located 18 mi (28.97 km) beneath the Sword Mountains.

History
In 1154 DR, Ch'Chitl was founded by a cult of illithids that planned the settlement as an adjunct to Skullport. Around 1250 DR, a surprise githyanki attack led to the mortal wounding of the Elder brain.

The town was ruled by a council of elders after the death of it's elder brain. Ch'Chitl was devastated by the Spellplague in 1385 DR and many of the illithids were horribly spellscarred. Three of the elders were merged into one being which became the settlement's new elder brain. The remaining illithids acquired extraordinary psionic powers from their spellscars.
