At this point there is no reason for highlanders to not have Eyebrows
Lore accurate was thrown out the window a long time ago when Lyse, a Highlander and leader of the Ala Mhigans was given a head that looks way more like a midlander

If the Devs don't care about being lore accurate for one of the most prominent Highlanders in the story, then why should Lore accuracy be forced onto the players?
