Optional Mimir boat story

This story tends to be missing from compilations and playlists, because it only happens if you first open the shrine, hear the Hrungnir story where he is killed, then cycle through loading-sequence stories (using various elevators and traveling using the portals or between realms) until you get one where he mentions Magni and Modi, then you proceed with the story until after the escape from Helheim and reuniting the Dwarves. Now the story is available within a few times you enter the boat.
