As part of the Morag Tong quest to execute a writ on Navil and Ranes Ienith I got into a scuffle with Orvas and killed him... I am not yet Horrator of House Hlaalu.

I'm asking if this is going to be a problem (is he a required player in that respect)? But please answer, to the extent possible, with Yes or No. (i.e. I'd prefer minimal spoilage.)

Thanks in advance.

If he;s required for the Main Quest, you should've seen a message that said something along the lines of "With the death of this character, the prophecy is broken. Reload a save, or continue in this doomed world."

I'll take that as a "no"....
