Regulator

The Regulators are a race of dream walkers.

Biology
The Regulators are eldritch beings appearing to be humanoids with legs like spiders. Their heads are shaped like those of a leech with many teeth. They are normally dressed in black cowls to hide their monstrous features, but are capable of shape shifting to suit the preferences of onlookers. They are capable of traveling between worlds, and manipulating dreams and those of others. The Regulators can manipulate those to sleep with a touch or even erase memories.

History
The Regulators traded with ancient man who visited their world through dreams. When the Gatekeepers came, the peaceful Regulators became enslaved. They were given orders wipe all trace of other worlds from humanity's collective consciousness to prepare for an invasion that would begin within a millennia. They were nearly successful however humanity's subconsciousness proved to be difficult to fool as it yearned to discover the truth, forcing many Regulators to remain on Earth to totally wipe out all remnant memories.

One Regulator managed to free himself from the Gatekeepers and hid on Earth as a dream merchant. He became instrumental in halting the Gatekeepers invasion of Earth.

Culture
Despite their monstrous appearances the Regulators were a peaceful race of dream traders. However when the Gatekeepers invaded their realm, they were forced to become slaves and act as their shocktroops in their armies.
