Straugh

When skirmishes break out between tunneling ghouls and creatures that dwell beneath the surface of Golarion, there's a chance that ghoul fever could infect such animals, producing strange new variants of ghoul beasts. However, letting the natural corruption run its course sometimes results in unsatisfying monsters, so some necromancers speed the process. This is the situation that led to the creation of the first straugh. A priest of Kabriri made the monstrosity to defend a claimed cemetery from another sect of ghouls who were preying upon the interred bodies. In some places, ghouls use straughs to tunnel into rival warrens or highly fortified mausoleums.
