Jiub is a Dunmer prisoner who is encountered in the boat in which the Nerevarine is being taken to Morrowind. He later achieved sainthood, and hundreds of years later, his soul had been trapped in the Soul Cairn.
He was transferred by ship alongside the Nerevarine from the Imperial City prison to Morrowind for release in 3E 427. When the Nerevarine awakens, Jiub tells them that they were asleep for a long time, and nothing would wake them up, finishing the coversation by mentioning that the ship has reached Morrowind. After this short, initial encounter, Jiub is never encountered by the Nerevarine again. He is the very first character the Nerevarine encounters in Morrowind.
- The soul of Jiub can be encountered in the Soul Cairn in The Elder Scrolls V: Dawnguard, where he asks the Dragonborn to get the ten pages of his Opus so he can complete his life story.
- Jiub is also mentioned in The Elder Scrolls IV: Oblivion as Saint Jiub. "Saint Jiub's Day" is celebrated as the day in which he drove off the Cliff Racers from Vvardenfell.
- Jiub was killed by a Dremora during the Battle of Kvatch in The Elder Scrolls IV: Oblivion.
