Return of Reckoning

I tried running the quest Uzkular from KaK and it sends you to a Mourkain Tomb in Marshes to kill an npc named Flesheater there.

The tomb itself is easy enough to find, but there is no such npc in the entire cave. I made a video to show the whole cave: https://streamable.com/g41dqi

Could it be that it was forgotten to be added to the game? Has anyone finished this quest?

You were in the right spot but looked in the wrong place He's behind the wall: Sometimes you have to wait a bit since he fights ghouls and unfortunate dwarf there and can die: Good hunting!

Ah, thank you!
