In Norse Mythology, Eir a goddess and/or valkyrie associated with medical skill. Eir is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources; the Prose Edda, written in the 13th century by Snorri Sturluson; and in skaldic poetry, including a runic inscription from Bergen, Norway from around 1300. Scholars have theorized about whether these three sources refer to the same figure, and debate whether Eir may have been originally a healing goddess and/or a valkyrie.
- Eir is known as The Healer, an oddity amongst the Valkyries as Eir was very quiet and calm. Where her sisters were violent, Eir was gentle, healing mortal and god alike.
- Eir's defensive maneuver of shielding herself with her wings count as a blocking move; Kratos can break the defense with the Shield Bash (double L1) like he could with shielded reaver. Taking advantage of this could save a lot of time, as otherwise, Eir's does not leave many opening in combat.
- The same strategy also works on Sigrun.
