The Coliseum Morpheuon is a settlement built upon a semi-stable island in the Plane of Dreams. Erected by the Khan of Nightmares aeons ago, the Coliseum Morpheuon is more properly the settlement and ancillary buildings that serves the island’s centerpiece, the Chimeric Amphitheater. Given its draw as both a sports stadium, gladiatorial hub, and major trading post, the Coliseum Morpheuon sees many dream-travelers pass through the place daily.

The Khan has many safeguards to keep order in this place, but chief among them seems to be the “Voracious Visitor,” a black spot that hangs in the sky. It is unclear what this entity does, but everyone seems thoroughly afraid of it.

In addition to the Chimeric Amphitheater, there are several other smaller venues for competitions, as well as the sprawling market known as the Tarnished Souk.

The Shields of the Sorrowfell arrived in the Coliseum Morpheuon to rescue Ekaterina when she was trapped by unknown forces.
