Scáthach, meaning "shadow" in Irish, is the queen and gatekeeper of the Land of Shadows. She is talented with both the spear and rune magecraft. She has capably taught many disciples, including Cú Chulainn, and is often called Shishou (master). A magic red spear is her weapon of choice.
Scáthach has become half divine is no longer able to die normally, which is something she laments. She has a regal attitude and tries to remain aloof of current events.
