Sphere of Sarenrae
Urgathoa is the furthest planet from Sarenrae. It is a planet of the dead. Ruled by a council of powerful Liches. There are obsidian ruins of a ancient civilization that predates any in the sphere.
The city of Change
Built as Abadar’s distant colony and opened as the gateway to the outer sphere. A vast gateway to the other spheres was constructed here. The gate proved its undoing as it was invaded by the by terrifying creatures of undeath that conquered the colony. Now this is a city of the dead where vampires congregate and the slave markets and pleasure palaces operate. This is this only place were the living are safe on the planet, and even then the safety is debatable.
Urgathoa’s only moon, more of a small dark star, which is majorly negative energy dominant and surface is patrolled by wraiths.
