When inquired about his nickname, he will reveal that while on a job in Windhelm with Vex, their client alerted the authorities to their presence in the city. They were pursued by the guards and got separated. Vex was able to lose her pursuers rather quickly by blending into the shadows; however, Vipir was not able to lose the guards and ran out the main gate and ran all the way back to Riften. Upon arriving and seeing Vex and the rest of the Guild laughing at him, he only then remembered that he and Vex had left their horses just outside Windhelm. Vex had ridden hers to Riften, arriving hours earlier. Once he is done telling his story, he asks the Dragonborn not to tell anyone.
Vipir the Fleet is the Master level trainer in Pickpocket. He will only offer this service to the Dragonborn if they are a member of the Thieves Guild.
- Vipir can sometimes have unique dialogues with other members such as Thrynn, Sapphire and Niruin.
- Unlike the other members of the Thieves Guild, the Dragonborn can give him a Book of Mara which he will respond with "Are you out of your mind?".
