Another great video! About berserkers, there is a theory that theyd consume psychoactive mushrooms before battle, but that's just speculation. What's more certain, is that a "berserker" was a notorious killer. They were people who liked killing, whether it was in battle, in a duel, or just outright murder. Norse society was very violent, and in such an environment ruthless killers flourished. Anyways, this show does stylize the violent scenes, but in general it's actually one of the more realistic depictions of vikings in popular media.
