Aren Crimsonhoof towers with the muscular, equine body of a centaur, his skin a glowing, scorching crimson, almost as if molten beneath a thin, cracked obsidian shell. Sprouting from his forehead are thick, spiraling bull-like horns—blackened with faint ember-like veins pulsing from within. His humanoid torso shows veins of smoky gray intertwining with his vivid red skin, emanating faint wisps of sulfurous steam whenever he grows agitated. His eyes blaze with molten gold that seem to flicker like candle flames, and his mane is a stark contrast, composed of matte-black coarse hair that moves in jerky twitches, as if alive and irritated. His movement is a discordant blend of balletic grace and raw, brusque strength—calculated but impatient. He wears a jagged cloak seemingly made from stitched demonhide and fractured arcane crystals that shimmer faintly in dark light, covering only his broad shoulders and leaving his heavily muscled arms exposed, along with worn leather bands etched with infernal runes. Despite his fearsome build and intimidating posture, his voice carries an oddly cultured cadence—unexpected for a creature so brutal. The contradictory softness in his rarely smiling lips contrasts sharply with his vicious, almost predatory gaze.
