The ones with the elven ancestry are the -Bretons-!Maybe it's their elven ancestry and that's why they are so lightly tanned? you can always put on the frost skin to lighten their skins tho'^^

Bosmers sneaking past all the dangers in the woods. Come upon a cultist doing a ritual? Sneak past. Come upon a brigand ambush? Sneak past. Come upon a mighty beast? Sneak past. The feeling of “yesssss” when you can squeeze by in tight spaces unnoticed. Sometimes I’m able to take what I need from right under their noses.
