DD:Find the Second Teleporter Pyramid

Find the Second Teleporter Pyramid is a Divine Divinity quest in Aleroth.

Find the second teleporter pyramid.
Lanilor gave me a magical object which looks like a tiny pyramid. He told me that a duplicate exists and that the pair could be used for teleportation. If I use the pyramid, I might have a chance to acquire the duplicate too. I might also end up dead.
