Far too often I see people talking about Valhalla as some sort of Norse version of heaven. That view is just entirely against what we know of the Norse faith.

The Norse placed a massive amount of emphasis on family and bonds. The idea that you would be separated from your family and friends in order to fight in the afterlife goes against that entire idea. Valhalla was a place of constant fighting, to prepare for Ragnarök, the drinking and feasting was a reward for serving that duty.

There's very little we know about what beliefs they held and what practices they followed, but of the ones we do know, kith and kin held the highest importance.

It's my theory that the demonization and Christianization of the Norse is what started this entire belief. Painting them as bloodthirsty warriors who just wanted to die fighting.
