Мед Квасира

Kvasir was a dwarf formed by the gods after the Aesir made peace with the Vanir. He wandered through the nine worlds and was highly regarded everywhere. However, the two dwarves Fjalar and Galar wanted to steal Kvasirs' talents. So they killed him and mixed his blood with honey to form a mead. Drinking this mead will allow you to travel the worlds like Kvasir.

After drinking the mead, you'll be able to step in the Portal to Alfheim and travel to Alfheim yourself. If you accidentally break your portal in Alfheim you can fix the frame and throw some pixie dust in. When it despawns, the portal will reopen.

By using a wandering trader as a symbol for Kvasir you should be able to get blood to form the Mead of Kvasir.
