Ethereal Energy Being in a Gothic Vampire Castle

An ethereal energy being, a translucent humanoid formed from crackling electric light, glowing cyan and white with a radiant core, hovering inside the throne hall of a vampire castle. In anime style with bold cel-shading, dynamic pose, and vivid color. The gothic chamber features towering stone arches, ornate gargoyles, crimson velvet banners, and stained-glass windows that spill moonlit red and violet light. Chandeliers cast warm candle glow while bats flit above. Energetic tendrils trail from the figure, weaving runic sigils on the floor as it surveys the room. A cinematic, low-angle composition with dramatic contrast between cool energy hues and warm ambient light, dust particles floating in the air and a sense of ancient power.
