Legend of the Abyss
The Endless Ocean
The Endless Ocean stretches across the face of Abyss since the Tearing. It is called endless for the fact that no one has ever explored it fully, the intense storms of the surface have made navigating it nearly impossible. The Gnomes have managed to map some of the lower depths and underwater tunnels that stretch into the depths of Hallrgard.
It is said that Halflings live out on the Endless Ocean, but these accounts are rare and highly speculative.
