The Gortach is base don the Celtic fae known as a Fear Gorta or "Man of Hunger" a fae spirit that roams the land appearing emaciated and begging for alms. I took the fae and the intelligence away, making the figure an undead. The alms begging, however, translated into the creature mechanics through an "unconfirmed" rumor which could allow the Gortech to be taken care off without a fight.
The howls of the wind in the arid lands are filled with the moans of the dead who Hunger claimed. Keep your waterskin close and your foodstuffs closer for if the Gortach smells what it was once denied I fear you too will be denied.
