K'gil'mnon is an unidentified reality, a "nightmare realm" which seems very nebulous, perhaps similar to a small galaxy. It is home to and ruled by the Outer god Kaalut; it is also inhabited by his parasitic insectoid servants, the Gharoides. Whether any other entities inhabit K'gil'mnon is unknown.
Behind the MythosEdit
It was introduced in "His Hour Upon the Stage" by J.B. Lee, published in the e-zine Nightscapes in 1998.
