Arantham appears tall from a distance, but this is due to his slender build and skeletal form; he’s of roughly average height. The priest is entirely skeletal, with barely a trace of flesh remaining on his body. He still has hair atop his head that is a stiff and faded gray somewhere between the hair of a dying person and a clump of moss. His eye sockets gleam with an inner gray-green light; his bones have the faintest sickly green tinge to them, and his teeth are perfectly white. Elder Arantham wears a ceremonial robe of snowy white hue, trimmed in the traditional black and red of Orcus. When going into battle, he wears a shirt of scale atop it. An amulet of black wrought iron, bent into the shape of a horned skull, hangs from his neck.

Though he rarely shows overt anger, even when thwarted, Elder Arantham holds his grudges eternally. Anyone who forces him to experience the shame of running can expect repercussions to come. Elder Arantham is a master of rituals.
