The universe has fallen into a state of complete heat death save for a single photon surrounded by an unimaginable void. Once this photon is destroyed only then can the universe begin anew the cycle of rebirth. That last step is the destruction of Lumen, the world of Lightmare. Lumen is a photon haunted by the psychic echoes of life that has perished aeons ago. Lumen is in denial that it must be destroyed and refuses to die for when it dies, there will be no record of any life having ever existed. It is the concentrated psychic denial of Lumen that has allowed it to exist for as long as it has. However, all things come to an end. The players are agents of entropy sent forth by the Void to bring an end to the very last thing in the universe.
