The Dink Network

Hello, I'm kinda stuck in Morabia. I have defeated the slayer and now I cannot find the next step. The bridge back is still (?) broken and I cannot find the cave with the missing girl (I have found two caves but the girl is in none of them). Can anyone give me a hint what I should do next or where I find the girl?

I am stuck in this exact spot as well.

Go to the wizard south of morabia and move the rock just north of his home. That will open a cave entrance allowing u to find the girl and progress.
