I'm gonna try to make a build for him. I finished Dishonored (finally) last week, and I just got this inspiration all of a sudden to make him. He'll be an Imperial, and side with the Empire. Though I don't think I'll make him do the quest, I just want him to be in the Empire...cause he's the Empress' Lord Protector.

Skills I think he'll use:

Sneak
One-Handed
Block
Illusion (for Possession)
Archery (Crossbows)
Detect Life/Dead (Dark Vision)
Alteration (Mage Armor, for survivability.)

Shouts:

Whirlwind Sprint (Blink)
Cyclone/Unrelenting Force (Wind Blast)
Aura Whisper (Dark Vision)
Slow Time (Bend Time)

He'll wear hoodless Thalmor Robes, no gloves at all, and Fine or Leather boots. For his mask, a Dragon Priest mask. Maybe Hevnoraak or Krosis, I'm not sure yet. I'm not on PC unfortunately, so I can't get his armor mod.

Anything I should add to that?
