Dragon Age: Ascension
Simple young surface dwarf, skilled rune enchanter.
Sandal and his adoptive father, Bodahn Feddic are surfacers, dwarves who have left Orzammar for the surface to have dealings with humans and other species. Bodahn found Sandal abandoned during one of his many expeditions into the Deep Roads, and has since adopted him, caring for him as if a biological son. According to Bodahn, Sandal may be lyrium addled due to the exposure to lyrium in the Deep Roads.
Bodahn claims the Circle of Magi declared Sandal a savant. As such, Sandal is unable to care for himself, and has a limited mental capacity for common tasks (such as conversation, where he usually replies with one word answers), while excelling at rune enchanting and, to a lesser degree, runecrafting.
