Recent Game Tribute
This is kind of a weak idea, but in the newest Elder Scrolls game Skyrim: I made a weapon that traps the opponents soul inside of it. I called it "Soul Sucker" in name of Ozzy's amazing song.
Which lead me to believe, why isn't Ozzy a Daedric Prince of Oblivion in the game?
Here me out:
His artifact could be called "Soul Sucker".
You have to wait until the Moon is out to summon him by offering him a bat.
His priest could be called Perry Mason or Crowley.
You must kill a special NPC called "The War Pig" for him.
The only downside would be that you NEED subtitles to understand him ;)
