Vonwacq is a small and crowded planet, almost entirely covered by rainforests and islands, with its exuberant wildlife being its most recognizable feature.

Vonwacq’s effervescent vitality made the rainforests near its equator grow so large and tall that their shades would cover the sky above and even block out the sun. The lack of sunlight in the undergrowth of the rainforest throughout the year creates a perfect space for fungi and other low-light plants to grow. Intelligent creatures inhabited regions near the tropics. Plants, irrespective of height, would grow naturally here. Fresh fruits and vegetables could be picked at any time and anywhere, which was what the locals mostly fed on.

However, be it the new immigrants or the indigenous Wacqwacq beings, they have always maintained a quasi-religious reverence for the animal fruits growing on the Thestang tree.

The great Thestang tree never stopped bearing fruit, not even for a moment. With time, all those yellowish and translucent oval-shaped fruits grew larger and heavier, hanging down from the branches until the stems could no longer bear their weight. When the time came, fruits would fall to the ground with a loud and crisp sound, cracking their thin skin and releasing whatever was held within. The fauna of Vonwacq was all born this way, be it fish, birds, or polar bears. On Planet Vonwacq, creatures of all kinds shared one common birth mother.

The fiend known as the “Demon King” was also born from one such fruit of the Thestang tree. From the moment of its birth, it instinctively knew how to swing its giant ax-like pincers toward others, waging war upon the entire biosphere of Vonwacq.

Every sixty natural years, the Thestang tree would give birth to a new demon king, and the cycle went on and on. The people of Vonwacq had long been used to and prepared for such cyclical fates of doom. Whenever a demon king’s awakening approached, they would temporarily set aside their disputes and work together, assembling their strongest warriors to set sail for Wacq Island… One sixty years after another sixty years, these seemingly pointless crusades had been launched over and over again for hundreds of years in such narrow landscapes on this small planet. The demon kings were the permanent disaster of Vonwacq, and the caches of civilization were periodically wiped out.

Thus, it could be said that Planet Vonwacq was more like a stagnating pool of dead water, even though it was teeming with lively creatures that were ceaselessly fighting with each other, seemingly full of possibilities for change.
