Grimmer still progress glitch

I get that this is 100% my own fault, but friend wanted to level, took me to the reaper marsh before I'd 'naturally' unlocked that area. Finished grimmer still before even starting the questline with the new selvenar. Now Khali is no where to be found, can't progress into door into moonlight and I'm just kind of stuck and unable to progress in this story line...

Any help would be appreciated
