Einherjar

The einherjar are Odin’s warriors, chosen by the valkyries from those fallen in battle. They pass their time fighting during the day and feasting in Valhalla at night. When Ragnarok comes, they will march out of Valhalla and fight alongside the Aesir against the giants.

Asgard's finest. A warrior of Midgard wants nothing more than to fall in battle. It would ensure passage to Valhalla, a promised land where the honorable and wretched alike are sent. There, Odin selected the best and gave them another chance to die for him. Thus, creating the Einherjar.
