The ancient trees of the Shadowsong Forest have borne witness to the passing of epochs, and hidden beneath their dark canopies are the remains of empires long departed. Few souls brave enough to explore the primeval forest ever return, for countless horrors haunt the crumbled ruins.

The trail leads to the heart of the woods, wherein looms the greatest secret of all — the Pyramid of Shadows.
