Geography: This region encompasses everything west of the Gelf River, stretching north past the Bay of Rebirth and south to the ocean. It is defined by one dominant feature: The Forest.
It is a landscape of jagged mountains and deep valleys, but unlike the rocky peaks of K'thari, these mountains are choked with ancient, colossal trees. The canopy is so thick that the ground floor is in perpetual twilight. It is a single, unbroken biome that has stood since Year 0.
The Gelf River is not just a boundary; it is a wall.
The East Bank (Galax County): Low, flat, and marshy.
The West Bank (The Weald): A sheer, vertical limestone cliff rising 200-300 feet straight out of the water.
The Strategic Effect: This cliff acts as a "massive fence." The fiends and monsters of the Forsaken Demesne cannot cross the wide, deep river and scale the cliffs. This natural fortification is the only reason the horrors of the East haven't spilled over into the West.
Where the forest meets the southern ocean, the land doesn't slope down; it shears off. The coastline is a jagged, 300-mile run of sea-battered cliffs.
The Citadel of the Morning: Perched on a high promontory 50 miles west of the river. The monks here look down from their white stone fortress into the churning sea. Behind them is the impenetrable wall of the forest; in front of them is the infinite ocean. They are the watchers on the wall.
The Hollows (Slade's Prison): Located 250 miles further west. Here, the cliffs are honeycombed with sea caves. The Cult of Lilino hid here not just because it was remote, but because the dense forest above made an overland approach impossible. The only way in or out is by sea, perfect for Oricon submarines.
This "Endless Weald" continues north for over a thousand miles, eventually wrapping around the Bay of Rebirth.
This explains why Seacliff (the timber town) and Greenharbor (the nature town) are so resource-rich. They are sitting on the edge of the largest forest on the continent.
It also explains why Alwyn's Hope (110 miles south of the Bay) feels so isolated. Alwyn didn't just build a town in a clearing; he carved a niche out of a primal, aggressive forest that is constantly trying to grow back over his walls.
