Go to Uruthumheim as Odar instructed, and search for the whereabouts of the Nornir.

"Well, we have to fight them eventually anyway. We may as well smash our way through." Following Odar's directions, you headed to Uruthumheim to search for the Nornir. At the Abandoned Site, all that remained was the body of a Nornir murdered by the Blades, with no sign of Urd, or any meaningful traces of the Nornir. Fortunately, Nemon discovered a Nornir survivor at the Northern Altar.
