Even if you count Vishi, the world secret realms they have truly come into contact with are only the Flowing Gold River, Dream Heaven, and the Wish Pool.
Among them, the Flowing Gold River is no longer a "secret" realm; it's practically a public domain. As long as one is a Two-winged Mage, they must have encountered it. Even if they don't understand the significance of world secret realms, they can discover two distinct features from the Flowing Gold River:
① It automatically produces Technique Spirits;
② It has a permanent effect.
Before Dream Heaven shattered, mages could acquire Dream Entry Technique Spirits from it—one of the main materials of Faded Dream Technique Spirits is Dream Entry Technique Spirit—but to obtain a Dream Entry Technique Spirit, one must pass through Dream Heaven's natural test; otherwise, it wouldn't be a difficult obstacle on the Path of Origin.
