Walkthroughs for the Main Quest series from Dibella's Watch, a large user created plugin for Oblivion. The defeat of the Deadtree forces at Dreadmoor Hills in Commander of the Army mean that only the Deadtree Clan leader in Temple Dro-Zharrn needs dealing with now.
Into Temple Dro-Zharrn
Talk to Captain Renck to start, and he asks you to do a favour for him if he dies, and go see his wife in The City. When you are ready to enter the fort tell him "It's time. Let's take on Dro-Zharrn!"
"We're now on our way to attack Fort Deadtree and Temple Dro-Zharrn; we're on our way straight into the Deadtree centre, but we need to do this before The Deadtree Leader uses the Dibella's Wrath to destroy the world."
"Dibella's Messenger has appeared to me again. She tells me that the war is now over, both in the realm of the gods as well as in the land of the mortals. I shall now go and tell the Count what has transpired during this final battle."
"The Messenger spoke of a wedding taking place at the Cathedral of Dibella, a wedding that, according to her, prophecies the coming of a new era in the land of Dibella's Watch. I am going there to see what is happening, but I have my suspicions."
"The Count tells me that Renck's widow was last seen at the Howling Drinker, which is a tavern of bad reputation in The City. I shall go look for her, since I feel it's my duty to take care of her for Captain Renck."
"I have found Renck's widow. Hard times have fallen upon her and she's looking for work. She would make an excellent maid in my Scarley castle."
Speak to her again and say "I offer you work at Scarley." This completes this quest and the Main Quest series.
