Planet Vast Expanse is the location of the Vast Expanse School. The size of the planet could definitely compare equally with the landmass of the Immortal God Continent; however, if the lands on the planet were unwrapped and laid out flat, they would definitely dwarf that landmass.
The planet is surrounded by a dark yellow ring, which is made up of countless asteroids, large and small. Actually, the planet is hollow, and the inside is even larger than it is on the outside. The main part are the nine temple complexes: one for each of the Paragons of the Vast Expanse School. There are many cultivatin clans on Planet Vast Expanse, but the Vast Expanse School is the only sect.
