"Her own letter is an agreement to give the King of Worms her "first" (no, it's not her firstborn child) if he will arrange for her to be married to the King of Firsthold. He gives you a letter to give to Morgiah agreeing to the pact.
This sets up part of the story for the sequel to Daggerfall"
So... What does she mean by 'first'?
And what 'sequel' are they talking about? I completed Morrowind and never noticed anything. Am I missing something or are they talking about one of the spin offs like Battlespire and Redguard? (in which Ive never played)
