The courtyard of Skullstone Hold is inaccessible by foot. Only dragons and whers can get their riders here... or beings able to fly by other means. This community as a result is where most of Pern's dragonkin-Ferali live, as well as a large population of Therioi capable of shifting into flying species. There are plenty of other Ferali and humans here too, of course. Skullstone Hold is a mining and smithing Hold, established within natural caves high in the mountains. It is simply too treacherous to walk or ride a runnerbeast to, though mountain-bred whers are capable of navigating the harsh, nearly vertical landscape.
