Goat-Man

This hunched, man-like figure lurches with a strange, half-hopping gait. Tattered clothing hangs from its muscled shoulders, and its legs are those of a ram, ending in cloven hooves.
Trespassers on the Rites. The first of the goat-men was the victim of a powerful curse intended to punish him for spying on magical rites exclusive to the women of his tribe. Admiring the grotesque result, the Black Goat of the Woods With a Thousand Young adopted him as its servant, and ensured that all who committed the same taboo fell to the same curse, and thus into the Black Goat’s service.
Bleating Speech. A goat-man’s head is tusked, adorned with curling ram’s horns, and its beard often drips with gore. Rows of transparent, needle-like teeth fill its mouth; these teeth are malformed and make clear speech impossible for goat-men, though they understand others’ speech perfectly well.
Serve Foul Cults. Cultists of Shub-Niggurath or the Black Goat in good standing are sometimes granted the services of a goat-man. The creatures guard rituals sites, visit settlements to capture or purchase suitable sacrifices, and perform certain unspeakable acts with cult members to call forth ritual magic.
