Since Jauffre died long ago during my old playthrough, it wasn't until just now that I decided to create batch files which can resurrect either him or Baurus if they died during the main quest. I also thought it would make sense to have them roam the Cloud Ruler temple in ghost form.

To install, just extract the text files to your Oblivion folder. Then ingame, open up the console and enter "bat <insertfilenamehere>.txt" without the quotes.

I also made a mod which changes the visuals of ghost NPC's, which can be downloaded here.
