Knocker

The Knockers are breed of kobolds, though they are larger and stronger than typical kobolds. Inhabit various adits, grooves, precipices, chasms, dark cavities, burrows, delves, grottos, caverns and rocky heaths. Their existence in area is always evidence for the presence of wealth hidden in the ground, such as ores, minerals, salt or petroleum. Considered as the malecious rogues and pests, and the real scourge for miners who they tantalize and haunts by knocking the rock, steal or destroy sidewalks, mining equipment and all possessions, sometimes even attack but stop at a few bruises. However, miners can get at them by food and alcohol.

Geralt met one knocker, a friend of Avallac'h, in the caves beneath Mount Gorgon. The knocker helped the witcher to get to Caed Myrkvid, serving him as a mount.
