This is an interesting quest mod. It allows you to join the side of the Mythic Dawn after you complete the main quest and help to retaliate. The quest is branching with different outcomes depending on choices you make.
Disappointed that the main questline of Oblivion once again forces you to be the "good guy," I decided to make this plugin for myself and all the players out there who wanted to more fully explore the Mythic Dawn faction. This plugin allows characters who have already completed the main questline to "redeem" themselves by joining the second wave efforts of the Mythic Dawn.
+ Starts where the main questline left off - continue with your existing character!
+ Expands the Mythic Dawn faction with a complete set of ranks and quests
+ Many new artifacts and powers to wield
+ Branching questline with several different outcomes depending on your actions
+ Dabble in the inner workings and politics of a Daedra cult
+ Command a host of followers, from acolytes to dremora
+ Rise through the ranks to become the new Master, or perhaps even more powerful...
Since your character will have already completed the main quest they will be at an appropriate level for this mod's difficulty. If you wish to design a new character for these quests you are welcome to; however, you will need to go through the main questline again first.
Unzip to your Oblivion/Data folder. Run OblivionLauncher.exe, select Data Files and make sure the checkbox next to the .esp file is selected. Then start the game. Once you complete the main questline (or if you load a saved game where your character has already completed it), simply make sure you are not in or near the Imperial City. You will be contacted shortly. =)
