DrashigWorld, described by the Fourth Doctor as both a "planetoid" and "dwarf planet", was owned by Lord Braye and turned into a theme park that housed dozens of drashigs. He claimed it was one of the 700 Wonders of the Galactic Hub.
The park was powered by a catalytic fusion reactor and divided into four quadrants, including wetland, desert, and rainforest, separated by energy barriers. Telepads were used to travel across the planet, but weren't used for internal travel within the Centre. (AUDIO: Planet of the Drashigs)
