The Umbra Nightmare - also known as the Endless Nightmare - and the Dream Watcher work together to maintain the world of dreams. They consider each other good friends.
The Umbra Nightmare was first among the two to be created. An accident as it was formed from the shadows that drip from Death itself. When many Pokémon feared their own deaths, that's when the shadows formed the Umbra Nightmare. As it roamed the planet, more and more Pokémon fell into a deep slumber, never waking from their nightmares. It grew and grew with each nightmare inflicted, though not because it wished to. There was no way for it to control its power. The Luna Terror noticed this and asked Life to help it create a being to control the Umbra Nightmare's power.
The Dream Watcher was formed from the essence of Life and the Lunar Terror. When it was formed, it rushed straight to the Umbra Nightmare. It could see the pain on the Umbra Nightmare's face and was able to, using the help of Life and the Lunar Terror, reduce the humongous beast down to a much smaller size. The Nightmare's appearance drastically altered too, weakening it so it would not cause nightmares where it walked. The Dream Watcher and The Umbra Nightmare now roam the land of dreams and nightmares, helping mortals through them. The Dream Watcher is aware of Destino's prophecy dreams, but is not able to affect or influence them.
