Hello, friend, and welcome to Solace Weyr, the dead-as-shit Dragonriders of Pern site which was recently liberated from invisible-thread hell. Nobody roleplays here any more, but this place is still pretty great. Feel free to stay a while and admire its quiet beauty.
There's more than one hatching cavern located in the Weyr; although the largest is used the most, there are several smaller caverns connected to it which are used by whers or non-queen dragons when they become egg-heavy. Although smaller than the main cavern, each has the same volcanically-heated sand floor and stands around the edges for spectator viewing.
