I really like the idea of getting unique set of armor for completing main quest and saving the whole Empire from being torn into pieces and devoured by Oblivion. What I don't like is that this unique armor is not so... Unique. In vanilla game, as all you know, it's just one of 3(!) retextures of imperial legion armor with stats of my grandfather's chamber pot. Lazy Bethesda. So I launched blender and started working on a new iteration of this thing.
What I ended up with is a stylish mix between antique and late Gothic armor pattern. All the meshes comes with corresponding ground meshes and icons.
Ah, and I changed stats of heavy armor to be something slightly better than ebony and altered the enhancement. It supposed to be the best armor Empire can offer.
Moreover, this mod replaces the quest icon for armor with one showing new helmet instead of old one, as well as replacing Tiber Septim's Armor and Emperor armor. Emperor's cuirass got unique model featuring all his imperial glory and animated cape.

You can get the armor in a usual way after completing main quest. Or, If you have done it already you can just take this armor on, meshes and stats will be replaced. But I recommend to unequip Imperial Dragon Armor and throw it out of your inventory before installing this mod, just in case.

For uninstallation you must delete Stav_ImperialDragon.esp from Oblivion\Data Folder and following folders

This mod is obviously incompatible with any mod that alters the same armor, in fact, I don't know any of them but WAC, which assign slightly altered mesh to the original armor. So you MUST load my mod after WAC using Wrye Bash or any similar tool.

You can play with my mod. For any other deviations please contact me first.
You can find me on the official Elder Scrolls forums as 'Stavroguin' or just use the nexus PM service.
