The mod have 2 armors:
1. Skuldafn Messenger, a light torso armor.
2. Skuldafn Armor, a heavy armor which exists out of arms, legs, head and torso.
Messenger can be found at the lab of Blackreach(When you enter Blackreach at the main quest, it is the first house.)
The heavy armor can be found at the words of ''Storm Call'' at the skuldafn temple.
There has been a update released, this update only exists out of a .esp file...you will need the main file too. With this update you can forge the armor and temper it... There will be coming an other update for tbe .nif file itself, so it will look more acceptable. -- Done deal, its the new main file :D

Enjoy!
