Coblynau are a type of small creature resembling gnomes or goblins whose roots lie in the folklore of Welsh folklore, though variants can be found in many areas of England (due to mining being a part of their history for generations)
Overview[]
a Coblynau is a type of gnome (or sometimes a benevolent goblin) found in Welsh and English folklore, closely related to Knockers but of a helpful nature - they are depicted as ugly little humanoids often dressed in traditional mining gear and they would work tirelessly in mines, they would aid miners in finding hidden gems and treasure via making knocking sounds and are well-liked for their friendly personality.
