Greenhilt is the surname of a family of human origin presumed to be from the mercantile city-state of Cliffport. The family is named after their ancestral weapon of the same name, which was notably wielded by Horace Greenhilt when he vanquished the dragons of Reddragonville and saved Princess Damsel. During Eugene Greenhilt's lifetime, he swore a Blood Oath to defeat the sorcerer Xykon, which has been passed on to his children Roy and Julia after his death. The current head of the family is Eugene's son Roy, who wields the family's ancestral sword and leads the adventuring group known as the Order of the Stick in efforts to stop Xykon and those who would attempt to use the gates containing the Snarl.
