Which dwarf holds the northern corner of the sky?

Norðri is the dwarf said to hold the northern corner of the sky in Norse mythology.

According to Gylfaginning, Odin and his brothers make the heavens from Ymir’s skull after killing the primordial giant. Because the sky is imagined as having four corners, the gods place one dwarf beneath each corner to support it. Norðri occupies the north, alongside Austri in the east, Vestri in the west, and Suðri in the south.

The names are directional Old Norse names: Norðri means “northern,” while Austri, Vestri, and Suðri correspond to east, west, and south. That makes this question a matching test rather than a story about a separate heroic deed by Norðri.

The four dwarfs appear in Snorri Sturluson’s 13th-century Prose Edda and are also reflected in poetic kennings for the sky. A common mistake is to confuse Norðri with Niflheim, the northern cold realm, or with the giant Ymir, whose skull becomes the sky they support.
