From a history of that ancient land of verdant forests and beautiful mountains, to the mythologies surrounding its creation and the gods who carved it from the ether, the realms they ruled and the monsters they commanded. This is the Codex Sinarum. It begins in the Age of Ancestors and mythic history of the Jade Emperor to the founding of multiple dynasties. From the dynasts to the lands both real and magical, divine and celestial to lands of legend and lore. All this leads into the plethora of magical beasts that stalk the wilds, that hound humans and all their progeny. And beyond all that lie the gods, from the furthest antiquity to the Yuan Dynasty. With them are the wizards and wise hermits and an ancient, very complex system of spellcraft. The Codex Sinarum ends on a warrior’s note, creating a core martial system for Castles & Crusades.
