The Primal Realm

Life on Orr began in the fertile jungles of the Primal Realm. Where the waters of the Sea of Mithris coursed through the rich soil of Nausica, green things sprung and the nameless ancestors of all living things mudfished their way from ocean, to river, then stream before crawling up upon the land. So long ago were these most primordial of events that they are known only in the jesting and whimsical philosophy of the greatest lyceums of learning in all of Orr.
Being the cradle of creation it is no wonder that Nausica's landscape is so diverse of life and ecosystems. Sprawling jungles filled with thousand-foot high trees hide entire worlds beneath their banana-leaf canopies. The great yawning deserts of the Primal Realm have swallowed dozens of civilizations before they ever carved their first hieroglyphic. The mountains of the Skybeyond Summits are catacombed with the world's earliest dark-dwellers, and the peaks themselves are littered with the bones of Giants so ancient and mighty that they have become little more than fossilized stone.
The Primal Realm belongs to monsters and the beast races. It belongs to the Genasi and the vast multitudes of Outsiders that were driven from the civilized world after the Cataclysm. Within the tangled greenery of the jungles lie the golden cities of the Yuan-Ti, and the tree-top houses of the Tabaxi. Amid the gulping swamps at the foot of the World's Edge mountains are entire nations of tribalistic Lizardfolk and Grippli. Upon the wind-sanded stones of the Zarcanian Desert walk the last fleeting tribes of the ancient Gith, and upon their edges the children of Sylph and other Elementals travel in great caravans upon the backs of Dragontortoises. The mountains belong to the Giants, whom once nearly ruled this world of Orr, and their lowest summits are the roost of the Aarakocra and the Kenku. Amid the warm ocean waters that brush against the golden shores of Nausica lies the sunken coral cities of the Merfolk and the Triton.
Nausica is a land of mystery to the mortal races of Orr. There are secrets here to uncover for generation upon generation, but to reach them one must brave the beautiful, treacherous landscape, and its denizens.
None wander in the Primal Realm. Every footstep is made in expedition.
