Prompt

Emerging from the shadows, an undead centaur clad in ominous black armor strides with an otherworldly presence. Sinister green energy seeps through the gaps in his menacing armor, casting an eerie glow upon the desolate battlefield. Gripping a wicked halberd in skeletal hands, the undead centaur exudes an air of malevolence, a spectral guardian bound to the ethereal realm, ready to unleash death's embrace upon any who dare cross his path.
