The party takes a breath after fighting several bats and a Petch
The party finds a trail of fine sharp vibrating dust that leads down some stairs in the ruins. There are many pathways that have been walled off within the last century or so. A circular domed room is at the end of the crystalline dust. Has glowing purple crystals and a humming can be heard. The crystals detach from the walls and become crystalline entities of some sort that stun most of the party for a round and attack. The circular room has a map mural on it of Avistan from millenia ago which Abigail and Sanna decipher. Arik, recognizes the map as being from 5-10k years ago. We descend down the spiral staircase in the middle of the circular room several stories and emerge into a natural cavern with worked stone at the end of it with a door in it. There are several crystal infected goblins. Lascar monologues at as from around the corner atop a crystal globe on top of a crystal tree trunk. He has been almost completely turned to crystal, and by his own admission is no longer Lascar.
