Bandalong
The Tleilaxu Inner city. No outsider can set foot in this inner-sanctum, which houses your Kehl hall.
This is the heart of the Bene Tleilaxu Empire. Thousands of Bene Tleilaxians have walked its pathways over the years.
From Heretics of Dune
“The air of Tleilax was crystalline, gripped by a stillness that was part the morning chill and part a sense of fearful crouching, as though life waited out there in the city of Bandalong, life anticipating and ravenous, which would not stir again until it received his personal signal. The Mahai, Tylwyth Waff, Master of the Masters, enjoyed this hour more than any other of the day. The city was his now as he looked out through his open window. Bandalong would come alive only at his command. The Tleilaxu civilization had originated here and then spread its powers afar.”
