Quest Glitched out preventing the ability to move forward in the story.

Try typing /isearch wardstone into the chat window to make sure it dropped. Double check you're running the "normal" version of the dungeon, I know you said normal in your post but it's worth a check. Are you sure you have space in your inventory before you finish? Is there someone or something that appears after defeating the last boss of the dungeon? Sometimes things have to be triggered before you leave to progress further.

It has been a very long time since I undertook this quest so I'm only able to give generic advice. Sorry.

I did as you said
/isearch Belah'dian Wardstone
it came back saying "No matches found containing"Belah'dian Wardstone"
I also tried just wardstone and got the same results.

as for the dungeon, yes, I dont even have a hard mode version of it unlocked, but to make sure i shared screen with a friend who has been playing for the last several years, and showed him the process of queuing up for the dungeon and he even said I did everything correct and that I was running the dungeon on the correct difficulty. I should have also gotten it during the first run with my friend, as while I did not get the stone, he did, and was able to complete the quest.
