Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Main quest stuck at the mines

I think you mean you rescued Icara?

And you have to sneak past the Death Knights in the mine as you get the spell at the end of the mine level when you are using the mirrors to escape the three Death Knights Leandra summons. If you have the spell try to get Lysandras blood. If you didnt the spell, you can enter the mines again using the mirror in the forest east of the White Witch Hut.
