Okay, I just finished the 3rd part of this quest and I have to ask... Is that really it?

You follow Dralnok down into the giant labyrinth, you find his fate, get sent to find the axe and then have to follow after Ganesh. Then you're sent after journals, and when you finally get them you're told that he passed through the portal and that's the end of the line. Nothing else. No searching for a way to activate the portal and find where he went. Did I miss something?

I just started these, and am still trying to finish most of them so I am fully aware that there could be an NPC I missed. I hope so. Maybe some quest requirement I haven't finished or something.. I dunno.

Anyway, I'm not meaning to rant but simply ask. Is there more to this, or is this where it ends for now?
