Carcosa is a planet in a solar system far across the Dark Tapestry from Golarion. The planet is the home of the Great Old One Hastur, also known as the King in Yellow, who dwells by the monstrous Lake of Hali. When the light of Carcosa's star shines in another planet's night sky, Hastur's power on that planet grows stronger.
- ↑ The name and description of Carcosa derive from the real-world short story "An Inhabitant of Carcosa" by Ambrose Bierce and the anthology The King in Yellow by Robert W. Chambers. More information on the place can be found in these stories.
