It is said that at some points deep in the Unovan wilderness, reality stops working the way it should. Pokemon do not move around trees or climb them, but phase through them while they walk. Rivers and streams cease to run and turn still, while water pokemon swim upon dry land. And every now and then, at the deepest corner of this bizarre forest, a flash of black fur moves into a pit in the ground, or a cave, or a large bush, and reality warps behind it.
All of this is true, or at least it appears to be so, and none except the Zoroark at its source can reliably tell the difference. Zoroark are a rare pokemon whose considerable fighting power is insufficient to protect their nests from predators, especially given their low fertility rate and the slow growth of their young, so they instead protect their lairs through elaborate illusions. Zoroark do not only gather food, but also any item they consider treasure, and although their definition of treasure differs considerably from humanity's, it is said that a Zoroark lair rivals the greatest of Hoenn's secret bases in splendor.
Only a chosen few have ever claimed to be invited into a Zoroark lair, and these few are individuals renowned for some sort of greatness. Most notably among them, at least in recent years, was a mysterious boy named "N", who played a leading role in Team Plasma, could speak with pokemon, and was at times rumored to be a Zoroark himself. The marvelous castle which he built in the Pokemon League is said to be an attempt to recreate that lair with human tools, although both he and his rival maintain that the true homes of wild Zoroark are places far stranger, and far greater.
