What Lies Within?
The Fold is a zone on the eastern end of the Longest Road, sitting between Raven Spire and the Galifer mountain range. Created by Cyr, the Fold was the gateway used by the dragons as they left to another plane of existence. When Granvious passed through the gateway, the portal exploded, sending a shock wave over the Longest Road and creating a dead veil of air between it and the mountain range. The portal did not close and can still be seen from outside the veil.
Scholars, particularly those of Dragonborn heritage, theorize the gate was forced to remain open so that one day, Granvious can return when he is ready to challenge the gods.
Many have entered, for research, for adventure or by mistake. The lucky ones are transported to seemingly any location on Cyr-Myth. They tell of never-ending planes, roads that lead nowhere and everywhere, continuous lightning storms without thunder and a constant wail when night falls. The unlucky ones are never heard from again.
