The Bone Lord’s Horn is a sinister, twisted artifact resembling a large, curved horn made from darkened bone. Its surface is intricately carved with eerie, runic symbols that glow faintly with a sickly green luminescence. The horn tapers to a sharp point, with uneven, jagged edges that suggest it was torn from some monstrous creature rather than crafted by hand. The overall texture is rough and pitted, with visible cracks and fissures that add to its ancient, cursed appearance.
