So, i was versing Krosis, just after i'd killed the dragon (-__-), and my companion (ogol) died with the volendrung. He was also wearing orcish armour. When i managed to get back to get my items off him, i was able to get the orcish armour back but he did not have the Volendrung? I checked back at (i think it's called) Largashbur where ogol is from, and where i got the Volendrung on the ritual stone thing, and it hadn't respawned there. So it is lost forever, if not how do i get it back?

Any chance they were disarmed and Volendrung is laying on the ground some where near where they died?

With Ritual Stone,you ressurect a companion as a zombie and he lives forever?

ok i have gone from there, but if i fast travel back wouldn't it have reset and it wont be there? Or not reset. Thanks for quick replies

Went back and not there :/
