Elison

Background
Elison was married to Janak before he went off to Candle-Keep to study. After Vibaem transformed Janak, he sent word to Elison informing him that Janak had died. Elison somehow ended up being captured and forced into slavery, eventually becoming a unwilling lieutenant for the powerful Beholder.

Interactions With Mystic Obscura
Elison stood over the meeting between Xanathar and Mystic Obscura, seemingly identifying the group by sight, despite them having never met before.

Elison was released by Xanathar eventually, although it took time for his mind to be restored back to it's former self.

He was happy to see Mystic Obscura again when they returned home in Triboar, and thanked them profusely, doing so again when they returned Janak to his natural form.

Elison was upset for Janak when it was revealed Mystic Obscura weren't truthful with him regarding Vibaem, but explained he would understand in time.
