I read the Highlander suggestion. While I know he’s referring to making Tusk an immortal, that movie character’s ethnicity isn’t far from this Pict idea. I think the Highlanders occupied areas of Scotland around the same time as the Picts, if I’m not mistaken. Linguistically they may have been similar. I just think the Picts were more barbaric and lived off the land more than the highlanders, which makes them a little more appropriate for Tusk imo. I’d rather not see Tusk in a kilt.
Lowlanders, however, didn’t wear kilts.
If Tusk is not going to be a Pict, then Lowlander would be the next best thing.
If he can’t be a Lowlander, then maybe a Highlander.
But as I understand it, the Highlanders were more organized/civilized. (Not fitting for what most of us want from Tusk.)
But the Picts are often depicted as being the savages of Scotland.
If you saw the movie Eagle, that scary Seal Tribe was Pictish. (The director refrained from tattooing them because he was afraid they’d look too native american.)
