Man this dude was a beast, but you get some really cool stuff fighting him.

It does not involve the main story line, i found him on a mountain guarded by a dragon.

His mask/helmet has some great benefits.

Man i am enjoying this game so much, already became a werewolf! Found some ancient dwarf mine.

EDIT: His name is Krosis, you get a staff, his mask and dwarfen armor.

Where did you find him?

My bad his name is KROSIS, the picture is my character.

Il add a picture of where you can find him.

You get a really good staff, his mask which is good for lockpicking and archery and it has a good defense. You also get dwarfen armor from a chest.

Can't say I've met him yet, definitely seen his mask floating around a bit though. I DID, however, totally meet the headless fucking horsemen outside Whiterun! Ghost man with no head riding a ghost horse.
