Andvari (Twilight of the Gods)

Andvari was a dwarf who joined Sigrid's quest for revenge in Twilight of the Gods. He was voiced by Kristofer Hivju. He was a blacksmith capable of making weapons out of god-killing iron, so Sigrid went to him when seeking such weapons.

"Andvari" is the name of a dwarf who lives under a waterfall in Norse mythology, which may be a basis for this character.
