I ventured to a point of interest northwest of Glenden Wood and found this strange temple.
At its center, a spire shot purple lights into the sky. Perhaps the temple was built by the Empyrean, its purpose now forgotten?
As I explored the temple, at first, it seemed deserted. But, humanoid creatures appeared, called Shadows, who attacked with bow and magic. I retreated to the surrounding woods, and the Shadows watched, silently guarding the central spire.
Mayhap we could gather a party and return to explore further?
