A common breed of mostly nocturnal humanesque lifeforms suspected to be female, Dirts are most certainly a dangerous species. Hunting in packs they tend to pick off the stagglers of a group, pouncing as soon as they are alone.

It is somewhat common for male adolescents to intermingle with them, indeed it is seen by their peers as a right of passage.
