Einherjar

Valhalla is Odin's grand hall where the valkyries carry the brave warriors who have died in battle. Seemingly eternal feast is held to honor these guests - Einherjar. Valhalla has over half a thousand doors and its roof high in the sky is adorned with glimmering, golden shields. When the end draws near and the final battle begins, almost an infinite number of Einherjar will march through the doors to fight alongside with Odin.

Rostskur thinks it's obnoxious that every skald must have a song about Valhalla. It kills the originality of the trade!
