“Back when I was a regular mortal kid, I didn't know much about combat.
I had some murky ideas that armies would line up, blow trumpets, and then march forward to kill one another in an orderly fashion. If I thought about Viking combat at all, I would envision some dude yelling, SHIELD WALL! and a bunch of hairy blond guys calmly forming ranks and merging their shields into some cool geometric pattern like a polyhedron or a Power Ranger Megazord.”
