Graumths were a type of cave wyrm.
A huge insect-like creatures covered with bony plates that gleamed with an oily lubricant. Mandibles were at the centre of a flat, featureless head. Short spiky legs ending in huge claws that support its narrow, reticulated body.
Not afraid of anything.
Graumths were able to squeeze themselves to a quarter of their size to get through small spaces.
