So Klingons Are Essentially Space Vikings

From The History of the Germans Podcast, discussing the development of chivalry:

"This warrior culture relished fighting almost as fighting for fighting’s sake. They embraced not just the physical challenge, but also the inevitable consequence, i.e., lots of fighting means lots of death. But falling in battle held little threat for Norsemen, Goths, Franks, Lombards and Burgundians since an honourable death led straight to a seat at the feasts in Valhalla, where one could continue straight away with the fighting and drinking, presumably now without the risk of actual death."
