it's a common misconception that the Vikings had horned helmets. That notion was popularized by Scandinavian artists in the 1800's and Wagner in his Opera .. but it is not entirely true
In Japan, some Samurai armor incorporated a horned, plumed or crested helmet. These horns, used to identify military commanders on the battlefield, could be cast from metal, or made from genuine water buffalo horns.
I didn't notice the fur trimmings ... either way it's a cool colour concept x
