No one knows the size of the continent that sits immediately to the east of Hook Island. Efforts to explore the mainland have been generally unsuccessful beyond a few miles from the ocean.
While there has never been any known contact with an advanced civilization on the mainland, there have been discoveries of many ruins and abandoned structures that rival anything built from the old Rastarian Empire. Who or what built these structures or how long they have been abandoned is unknown.
Patrols on the mainland often encounter a variety of dangerous creatures but never any organized force.
