As a child, Rune washed up on shore after a shipwreck near Solitude, and was found by a local fisherman. Rune could not recall his past, but the fisherman found a rock with strange writing on it. The fisherman named him Rune and raised him, but he later left to discover his past. He admits that most of the coin he makes working for the Guild has been spent in vain trying to uncover his past.
Near the ladder leading out of the Thieves Guild Cistern, on the shelf of one of the cupboards, a note entitled No Word Yet can be found, which details the failure of a certain Athel Newberry's attempts to locate any details of his past.
- Dialogue with Rune suggests that he was supposed to have a Quest where you uncover his past, this would've been triggered by the dialogue option "I'll keep an eye out for anything"
