This creature's hairless, overlarge head surmounts its wet, wrinkled, and bloated humanoid body. Its eyes are glassy and vacant. Its arms are too slender, and its tiny hands end in cruelly sharpened nails, while its legs are atrophied, dead things that hang useless below it. Atropal scions are clots of divine flesh given form and animation by bleak-hearted gods of death. When a stillborn godling rises spontaneously as an undead, a great abomination is born. If that abomination is defeated, but any fragment or cast-off bit of flesh remains, an atropal scion may yet arise from those fragments, lessened in power from its divine beginnings, but no less hateful for its stature.

An atropal scion is a power to be reckoned with, and once animate in the world, seeks power over both life and unlife in an unrelenting bid for domination that only its lifeless tissue is able to sustain.

Atropal scions speak Common, Abyssal, Infernal, and Celestial.
