The dwarves are beings linked to the earth, skilled blacksmiths and goldsmiths so much to be able to make extraordinary artifacts, and able to give them portentous magical powers.
Their home is the underground realm of Nidavellir, under the ash tree Yggdrasill, the cosmic tree that united the world of men to that of the gods. Among the rocks and crevices of the ground, may lie the dark entrances to their subterranean realm, full of treasures. But each entrance is presided over by a guardian, and few are the those, among men and gods, who have permission to enter.
Nóri is one of these guardians, and it will not be easy to convince him to let you pass.
