Belmyne Dreleth is a demented Dunmer battlemage encountered when the Hero arrives at the Strange Door on the island in the middle of the Niben Bay. He is swiftly killed by Gaius Prentus or the Hero if they choose to intervene.
A guard, Gaius Prentus, has approached the Hero. He mentions that the people here have all returned from inside this strange gate, and all are now mad.
Gaius Prentus: "Here comes another one!"
Belmyne Dreleth: "It's not right! Madness! Why? Why? Everything is wrong! It can't be done! Stay away from me! I won't go back. I won't go back! You can't make me go back! I'll kill you all! You're all going to die!"
Gaius Prentus: "Stay back! This one's violent!"
