In the 12th chapter of the official site’s World Travelogue, we visit Pilaf’s castle. The design of this building looks like a mosque with the four minarets built on top of a pyramid. As part of the Pilaf gang, you have Pilaf who looks like a mini namekian kind of like piccolo after he was reborn, Shu a dog ninja with no ninja skills, and Mai the partner of Future Trunks in another timeline. This location is only used in the original series as they seem to live in Capsul Corp in Super. You can read all about it here ->
