The lost of sanity didn't came under that name but on another completely different. The Sandman explained us that he was neither malevolent, nor benevolent but that his only need was wanting to exist. But there was a problem : more and more his domain was being corrupted by creatures named "Nightmares" and they were stopping the prayers. They were causing the mortal that were dreaming to wake up. So he offered us power, but we had to accept the nightmares into our minds permanently. And, as he explained, it will drive us mad.

Coming of the Queen

But then, a new problem came. Our thirst for power was finally satiated but that power came raw. It was not ready for our use. We had power, but we could not use them. We became mad for nothing. We called again upon the Sandman. He understood but could not help, he said that an elf could help. A mighty elf queen explained and learned to our orders how to channel the power of the Sandman. She asked for one thing : we would become her armed arm. We did for years, we even created our own weapon and fighting style with the Claws, but something happened. Dark wizards saw her and wanted to use her has a power battery, in that process she was utterly destroyed but she had so much magic in her that she reformed in the Shadowfell as a new being. As the Raven Queen. And when she reformed there, as this new god, WE, the "power seeker" were freed from our pact with her. And we named ourself "The Dreamers" in souvenir of what is constantly affecting our mind. At this time there was a fracture.

The Raven Queen had been a ruler, yes. But a great one. So some of the Dreamers contacted her again and joined her ranks, serving this far away Queen. The other part of the newly freed Dreamers, started to go back to their roots, thanking the Dreamer for what he had offered them.

Servants of the Queen Has i explained, about half of my people, the Dreamers, joined the Raven Queen. She was now a god, so they acted has her clerics. The Raven Queen watches over the world, anticipating each creature’s death and ensuring that it meets its end at the proscribed time and place. By becoming her clerics and paladins they received more power, and a reason to live. They were to act as sentient crows, raven or pyschopomps, escorting the soul from the death of the body to the next destination. They have to make sure the machinery of life, death and the afterlife continues without anyone finding a way to 'cheat' the game.
