-    description= _ "Rovers in many ways represent the ideal Dunefolk unit; flexible, mobile, equally effective in defense and offense as well as in ranged or close combat. They are most comfortable operating in terrain and environments common to them; the deserts and hills of their southern lands. Moreover they fight best at dawn or dusk, corresponding to the time when desert temperatures are the most reasonable."
+    description= _ "Originating from the nomadic wanderers of the open deserts, Rovers, in many ways, represent the ideal Dunefolk soldier: flexible, mobile, equally effective in defense and offense as well as in ranged or close combat. They are hardy inhabitants of the deserts and hills that they call home and experienced hunters and trackers. While lacking training as formal soldiers, the skills Rovers employ for survival in the desert translate readily to warfare. Their unique trait of fighting best at dawn or dusk corresponds with the time when desert temperatures are the most habitable."
