You gotta nip those prophetic figure heads in the bud.
Maybe Helseth was annoyed that the emperor kept dropping off random registered prisoners in Morrowind?
I can imagine that would have been a fun talk with Uriel:
Uriel: "King Helseth, its been a while. So, have you heard anything about a prisoner I recently had released in your province."
Helseth: "Oh yea, him, yea, he's dead."
Uriel: "So quickly, he only arrived a short time ago. How can you be so sure?"
Helseth:"Oh, I'm sure, no worries. I had the Dark Brotherhood take care of him for you."
Uriel: "What!? You mean you killed him?!"
Helseth:"Yea. Wait. Isn't that why you sent him here? To die? I mean, why else would you send somebody to this hell-hole??? [censored], I mean, if I wasn't the King I wouldn't even be here."
Uriel: "He was supposed to save the world!"
Helseth:"Oh, ah, my bad man... but hey, look on the brightside, his friend is getting rid of all those pesky cliff-racers for me!"
Uriel: :stare:
