The Immortal Realm is made up of countless smaller realms, each separated from its neighbors by barriers. The realms occasionally interact but do not interfere in one another's affairs. Still, conflicts sometimes arise and spark wars.
Lingdu borders the Rain Realm, though the two have little contact. The immortals of Lingdu have only heard that the Rain Realm has a young, beautiful empress who is still unmarried. They know nothing else about it.
Lingdu has an ancient tree called the Penghua Fruit Tree. It blooms once every thousand years and bears fruit once every ten thousand. All the immortals of Lingdu rely on it to cultivate and improve their powers. Though it only blooms once in a thousand years, each flowering period lasts a hundred years. When a breeze scatters its pollen, everything it touches grows lush and abundant. Cultivating near the tree can accelerate an immortal's progress. The Penghua Fruit Tree has borne only a few fruits in tens of thousands of years. An immortal who eats one can advance by a whole level, while one who has lost their powers can recover them. If a mortal eats one, they can return from the dead.
The Penghua Fruit Tree is the foundation of Lingdu. For tens of thousands of years, its immortals have relied on it to cultivate. If the tree falls, the immortals of Lingdu will perish with it. As the saying goes, while the tree stands, Lingdu stands; when the tree dies, Lingdu dies. That is why Lingdu has a guardian, a person chosen by heaven. Its current guardian is a woman named Yun Jin.
