Einherjar

In Norse religion the einherjar or einheriar were spirits of warriors who had died bravely in battle. The name is Old Norse for "one-army-ers" (singular would be einheri). It is often interpreted as "outstanding fighter", but might also signify "those who are all [now] in one army", because when alive on earth they were in many armies and bands, but now they are all in the Army of the Dead.
