My interpretation of D’endrrah and it's entry on wikipedia:

"D'endrrah (The Divinity) is a sort of blurry female entity of supernatural beauty, dwelling within her obsidian palace located on Mars' Moon Deimos. She lives in a hall composed of a myriad of mirrors that distort her appearance, which is that of a tentacled dark abyss. This Mythos entity is somewhat inspired by C. L. Moore's Shambleau, the illusionary Martian she-vampires of lust."
