Deep within the caverns lies a chamber with a giant floating extremely pure Khas crystal. It seems to house an artificial intelligence inside. It was the source of the heartbeat sound. It was here that the Dark Archon learned many secrets of the Xel'Naga by attaching himself to the vines. He was drained by the vines, then restored. During this time, he shared information with the giant crystal. the Chamber is virtually impossible to enter with all the Dark Templars lurking around the Carven.
