Arn is the alias of a old friend who fought alongside Olfrid Battle-Born in the The Great War. While visiting Whiterun he was arrested for drunken behavior. Arn is wanted for a more serious crime in Solitude that may end with his execution.
Olfrid doesn't want to see his friend die imprisoned, and has asked the thieves guild to send somebody to forge the prison registry.
- It is possible that Arn is in fact the Thieves Guild blacksmith, Arnskar Ember-Master who only appears after completing several thieves guild special jobs.
