Step 4 of 8 · Sacrifice and What It Buys
Mímisbrunnr, Mímir’s Well
Why this step
A second sacrifice. In Gylfaginning Mímisbrunnr lies beneath the root among the frost giants, and the entry says Odin gave one of his eyes as a pledge for a drink from it. The hanging and the eye are two separate stories of Odin giving something up, and the entries do not join them.
From the Lorebook
A well beneath the root among the frost giants, kept by Mímir.
