Niruin is a Bosmer thief who resides within the Ragged Flagon Cistern and can sometimes be found practicing with his bow. He is also a master trainer in Archery.
He was born and raised in Valenwood, where he brewed wine with his father and was quite successful, bragging how he had fame, fortune, a mansion, and a beautiful fiancee. However, he thought that life too boring and desired adventure and danger, so he joined up with Valenwood’s version of the Thieves Guild, the Silver Crescents. His father discovered this and forced Niruin to choose between the winery and a jail sentence. He decided to leave for Skyrim through contact he had with Delvin Mallory.
