From the perspective of the players, it's clearer to see that the celestial bodies overhead are obviously completely different planets.
And this also confirms a speculation that arose long ago—
Subspace technology can be applied to interstellar travel!
Currently, it is hypothesized that three conditions need to be met.
The first is that the two worlds are sufficiently close in their subspace coordinates, the second is that both worlds possess "Magic Power" capable of responding to the prayers of spiritual entities, and the third is that both worlds have conscious beings—or rather, believers—who are able to reach a consensus!
To make an inappropriate analogy, Saint Sis and Bayele are like native deities of the "Aus Planet," and besides the creatures of the Aus Continent who are very familiar with Their names and stories, only the players from the "Land Depleted of Magic Power" Earth know of Their existence and understand Their doctrines.
