Vaermina (Online)

Vaermina is the Daedric Prince of dreams, nightmares, and torment. She is involved in the Daggerfall Covenant questline in Stormhaven, serving as the mastermind antagonist by using her followers, the Supernal Dreamers, to extract punishment on High King Emeric. She is met in the Quagmire through a portal from Emeric's Dream, where she speaks through the Statue of Vaermina.

Vaermina's Gambit
In Emeric's Dream, once the High King is freed from his bonds, Vaermina will say to you ethereally "I would speak to you again, mortal. Come to the mirror, to Quagmire." and summon one of her mirrors to serve as a portal to her realm, the Quagmire. Once traveled through, Vaermina will talk to you through her statue, telling you of her intentions to make you her new consort. As you refuse, she will make you choose a mirror to escape, and will spawn you back to the her realm if you choose the wrong one.
