Bottar is a Nord child who can be found wandering Skyrim.
Bottar can be met in a random encounter in the wilds. He is one of the children—along with Sond—who will mark the location of Deep Folk Crossing for a small fee.
He and his friend Sond sell various Dwemer artifacts and random potions.
If he encounters a foe, he will duck for cover, like other children in Skyrim.
