The Skullstone Archipelago is a big area in the West, a collection of islands that lie in a big shadowland. The shadowland is said to be one of the oldest shadowlands in Creation.

Skullstone is ruled by a figure called the Silver Prince. He has several Abyssal Exalted captains working for him. Of these, the party has met Obsidian Dragon, and been up against Ebony and Ivory.
