Hastur, He Who Must Not Be Named, The King In Yellow.
A Cthulhu Mythos deity who is very easy to summon (simply chant his name three times) but gets extremely cross if his time is wasted, so be certain to have a sacrifice and request ready or at least, his favorite play, "The King In Yellow" ready to roll but beware as reading the script is apparenty known to drive people insane (see the account of how he destroyed the magical kingdom of Carcosa and drove its queen Cassilda crazy). Appears as a tentacle monster wearing a yellow robe.
While he is the father of Shub-Niggurath's children, he apparently stiffed her on child support. The two deities, their cults, and servant races, hate each other immensely.
