in trouble in the volcano

I still cant get out of the volcano cave. there must be a quest I have still to save.
Does anyone know the quest tag for "The search for the map" quest. This is the one I am stuck on.

Do have a teleport stone? - do they work for you?

Thanks Wulf. Yes I can get out that way but the opening near Dork's prison cell is closed and I don't know why? How can I use "setqueststatus"? What is the quest tag for "The search for the map" quest?

Mmmm….if i remember correctly the quest to find the map was instigated by Brent the guy working alone with his pickaxe, try —-> Brent_FindMap
