The Dark

The Dark is a being created by Progenitus. He is literally the embodiment of darkness. 
== History ==
He and the Light took turns observing the things that were created, in particular the beings on the planet in which Gloom's various campaigns take place. The two bickered about whose turn it was, and so Progenitus created Time to moderate them. The Dark became upset about how unfair it was that he only ever got to watch the beings sleep, and in his anger struck the Light. She was injured and he fled. 
== Campaign Two ==
During campaign two the party discovered a tower that in the Shadowfell that contained a partially complete machine. Kiono managed to repair and complete the machine, which was then used as a beacon of sorts to call the Dark back to the planet. He arrived imminently and attacked the party. Ephemera was able to calm him eventually, and the two spoke for a time. He expressed regret over his actions and wished to help her regain her former power. She explained to him that she could not do that until the asteroid had been dealt with. 
Upon returning to the material plane, the party received word from Lysaro that the Dark had gone to the asteroid and destroyed the remains of the net there. He had then taken over its position, holding the asteroid in place. The obliteraors were being fought off by "what we're calling dragons." While nobody is certain how long this arrangement will last, for the time, it appears to be a good thing, allowing Ephemera to complete the halberd without concern in that regard.

In his desire to learn about the world he had once longed to observe, he created an entity with which to explore the world. Using this form, they explored the world, learned things about it, and encountered the people within. They also absorbed Nox's dying form for currently unknown ends.
