River of Bones

An ancient, dried up riverbed, the River of Bones divides the Ajtazi Wastes from the uncharted lands beyond. The empty chasm is littered with the bones of colossal, long dead creatures and the foolish men who attempted to cross it. The Ra'Hakin believe the boundary it creates reaches beyond the physical realm, which is why so many expeditions sent to uncover the secrets beyond have failed.

The only documented attempts to traverse it and make it back alive are Sheba Uzuan's exploration team and the infamous adventurer Cranston Fick.
