The eastern approach to Fort Valiance carries travelers through rolling hills of distinctive red clay, where the earth itself seems stained with ancient blood. These are the Ruby Valleys, called by the Caledrian peoples Val-Thurin, the Deep Clay Lands. A patchwork of terrace farms cascades down hillsides in geometric precision — each stone wall and soil ledge representing generations of sweat and careful husbandry.

The red clay, rich with iron oxide, makes Ruby Vale uniquely fertile. Caledrian farmers cultivate distinctive varieties: deep-crimson wheat of unusual flavor, substantial root vegetables, and the prized Valthorne apples whose skin deepens to nearly purple when conditions align. These goods feed Fort Valiance's population and supply commerce toward Thalassia.
