Valkyrie

From OMGWiki

The Valkyrie are Heaven's Fighting Wing Division. Goddesses are good in nature, and aren't supposed to fight (sans Urd). So, when using their power must move beyond defensive, the Valkyrie must protect them. One of the most powerful of these Valkyrie is Lind.

In Norse mythology, they loomed over the battlefield, deciding who lived and who died.
