Prompt

A hellish, female form, with four eyes upon her face. Four twisted horns grow from her head. Upon her back are two large wings. Inset upon their bends are demonic eyes. She stands 20ft tall, and half a body taller than her cultists. Her crimson skin slightly shows blackened bones beneath its surface. She floats ominously, without much effort from her large bat like, blood soaked, wings, in her ritual summoning chamber.
