Valhalla

Valhalla — the Halls of the Chosen — is where Odin gathers the mightiest of the slain to feast and sharpen their weapons for the Last War. Warriors call his name in battle in hopes of earning a place there.

Gunnar bears runes carved in blood for Valhalla among the marks scarred into him at birth, alongside the rune for Hel — the two fates his unknown ritual may have been weighing between.
