Queen Ulara

Ulara is the queen and assumed second-in-command of the faction of Duergar that Vox Machina battles against during their time in the Underdark. She was a power sorceress, utilizing an array of high level spells.

In battle, she disintegrated the ceiling of the Emberhold's throne room, causing a flow of lava to flood the keep. She also dominates Grog's mind, causing him to fight for her. After the death of King Murghol, she retreats by teleporting away, taking the incapacitated Grog with her.

She is later killed psychically by K'Varn in Yug'Voril Uncovered.
