Dwarves and Doguns IV bug

I have been doing the Dwarves and Doguns questline.
During the fourth part, after you defeat Garaheth and are sent to the Rodoroc Palace to speak with the king, I turned around in an attempt to leave, as I am the type of player who messes around with stuff like that. The only issue is that it actually let me leave and there is no entrance back into the palace from what I can see, yet the quest is still telling me to talk with the king. Nothing I google is helping. Does anyone know what I can do?

 

maybe try going back to the colosseum-type thing where the portal to Garaheth is to re-trigger the cutscene. Also, it might be accessible with the tunnel from the slums in D&D 2

 

Ah, that worked! Thank you!

 

You're very welcome!
