A dark, subterranean cavern shrouded in a spectral green glow, where an ancient, skeletal leviathan floats eerily through the air, its massive, decayed frame adorned with luminescent white antlers that resemble twisted coral. The creature's hollow eyes pulse with an otherworldly light, casting faint, rippling shadows across the cavern walls. Below, the ground is littered with broken bones, scattered remains, and strange fungal growths emitting a faint bioluminescent glow. In the foreground, a lone, cloaked warrior with disheveled silver hair stands poised, gripping a staff crowned with intricate runes that radiate a faint crimson aura. Their fur- lined cloak ripples gently as if moved by an unseen wind, while their armor glints faintly in the dim light. The warrior gazes upward, their stance both wary and resolute, as though preparing to confront the leviathan’s ethereal presence. The atmosphere is heavy with foreboding, the air thick with the sound of faint whispers and the distant echo of dripping water. Shadows dance along the cavern walls, blending seamlessly with the soft, green luminescence of the leviathan, creating a haunting, dreamlike scene of dark fantasy and ancient dread
