Three hundred years after the genetic disaster "The Great Rupture" tore the world apart, humans huddled in the last fortress "Asselburg", believing in absolute genetic purity and viewing the alienated world outside the wall as a plague that must be eradicated.
However, in the "Crimson Wasteland" covered with highly toxic spores, the nomadic tribe "Dream Weavers" live in symbiosis with this crazy land. They can "weave" the life energy of the planet - ether.
Karen, a young dream weaver with wild and unruly power who was regarded as ominous by his tribe, became the only hope when a "grey rot" that could isolate the "ether" and bring about withering and death swept through the tribe.
In order to save his people, he must embark on a journey to the source of the disaster to find the legendary sacred object "Heart of the World Tree". But the iron-fisted Speaker of Aiseburg also coveted this sacred object, trying to use it to launch an ultimate "purification" to erase all "impurities" in the world.
A race about survival and destruction, purity and symbiosis begins. In the desperate situation of being hunted, Karen not only has to fight against enemies from the fortress of civilization and monsters deep in the wilderness, but also faces the terrifying power in her heart that can destroy everything.
He will eventually discover that the key to saving the world lies not in what you find, but in what you become.
