Raiders are men and move 4 tiles.
Archers are women and move 3 tiles.
Warriors move 4 tiles.
Shieldbangers move 3 tiles.
Theory: Warriors are men, Shieldbangers are women.
You may ask: "WTF? They have a beard!!!111", but i read about bearded dwarven women in many a book. So women can have beards in fantasy worlds, and seeing how Varls love their beards that may be the case.
What do you think?
