The Blood Reef is a nexus dimension sitting on the outer edge of reality, inhabited by higher beings.
It is a panoptic realm serving as the home base to the Triumvirate of Sea Gods after their escape from the Graveyard of Gods. The reef allowed them to observe everything that happened throughout the multiverse and use it as a waypoint to traverse across reality.
