The Underworld Horse Mount is a striking, otherworldly steed with a sleek, muscular build reminiscent of ancient Greek war horses, but with a supernatural twist. Its body is shrouded in a dark, shadowy aura, with glowing ember-like patterns tracing its veins, suggesting its origin from the underworld. The horse's eyes burn with an eerie blue flame, and its mane and tail appear as if made of smoke, constantly shifting and flowing as if alive. The saddle and bridle are crafted from dark leather and adorned with bronze accents featuring intricate underworld motifs, such as skulls and serpents, enhancing its mythical appearance.
