This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Nuno (Philippine)
A nuno is a goblin easily angered that will do harm to those who damage or disturb his mound, and will seek retribution, for example by causing the foot of someone who kicked his mound to become swollen. Nuno sa punso are also believed to inhabit places such as underneath large rocks, trees, riverbanks, caves, or a backyard.
The nuno are the spirits of the ancestors. When a tree is to be felled, or a piece of virgin ground broken, or on many other occasions, permission is asked of the nuno, in order to avoid the misfortune that would come from angering it. The nuno is described to be a small old man with a long beard, but differs from a dwende or dwarf of Philippine folklore.
