The Unknown Lands
Pinnacle of Light
Etched into the stone wall standing before you is a sigil of the sun, very similar to those found in the Lightvault. The outlines of a door are clear, and one of them hangs open.
The entrance to this bastion was found within the Crystal Cave. It might be the bastion mentioned in prophecy, and within were found the Knights of Silver. For more information, see Prophetic Premonition and Shards of Madness.
