Geolord Mottle

Geolord Mottle is a rare mob quilboar found near in the Razormane Grounds in Durotar. She patrols the Razormane camp, ready to beat back any intruders that dare threaten her comrades.

Speculation
Being the only geomancer in the area, she is likely the one who helped establish the Razormane Grounds and raised/maintains the quilboars thorns.
