The Orb of Vaermina, named for its patron, was an orb apparently used for scrying. At some point before 3E 433, it was in the possession of a wizard named Arkved, by whom it was apparently "snatched from the dreams of [Vaermina's] followers".. It was recovered by Vaermina's champion, who received the Skull of Corruption in return.
According to the Moth Priest Kellen, the Orb was used by Lord Naarafin—then in the service of Boethiah—to spy on Titus Mede II and his armies. It was recovered by the Forgotten Hero from the Emperor's chambers, who either destroyed or kept it.
