Nordic Dragons are a thing but they usually are due to shapeshifting gold hoarding dwarves that get too big for their britches.

In the Icelandic Volsunga Saga (late 13th century), Fáfnir is a dwarf with a powerful arm and fearless soul. He guards his father's house of glittering gold and flashing gems. He is the strongest and most aggressive of the three brothers.
