Winged goddess on a crystalline mountain above a swirling nebula

A beautiful female, winged goddess with spiraling obsidian KUDU-LIKE horns stands atop a jagged, crystalline mountain of rocks and skulls, surveying a swirling nebula of cosmic dust. Her hand is outstretched showing the galaxy the severed head of the god she slew. Her gaze is ancient and knowing, Her wings wide and majestic, her form radiating an ethereal, hyperrealistic glow against the dark fantasy surreal backdrop. She is the bride of Satan. The style is reminiscent of haunting surrealism and detailed dark horror fantasy illustrations with dramatic, cinematic lighting and heavy mood. Lean heavily on the horror aspect. She should be terrifying, menacing but beautiful. In the Style of League of Legends.
