Silly people. Chainslash was the mabi version of 'necromancy'. Feed off the bad vibes of others and put it to your own use, sacrifice your HP to use a skill, edgy aesthetic, OP for no good reason... It's got half the tropes right there - which means it embodies necromancy entirely, by the standards of our devs.
As for vikings... we have those two fishing boat people. They're basically vikings.
