Eir

Eir is the goddess of medicine and healing in Norse mythology. Considered the best healer and one of the Aesir, a race of Nordic deities. It is also among the servants of Menglöd, probably called a form of Frigg. In the Thulur Eir is a name of a Valkyrie. If all three figures denote a single goddess, might have been thinking of a sore healing and totenerweckende Valkyrie originally.
