So think about this idea:

There is already the temple for meeting astrally, the mega temple for large rituals, and the blacknet for reincarnation control and information sharing.

But what if we were to create a "space" to meet in for astral travel, something like that the Internet was meant to be all along, a place where people can either meet in astral travel, projection or even full on manifestation? A positive isekai place.
