Since something like a Secret Realm is labeled as 'exclusive', it naturally has an entry threshold.
Just like some guild-owned Secret Realms that are basically not open to outsiders. Even when they are open, entrants often need to pay a certain price.
It's impossible to control resources and not use them for profit.
Of course, the vast majority of exclusive Secret Realms aren't particularly important, and are actually similar to most Secret Realms, with no obvious advantages.
Only a very small portion of exclusive Secret Realms hold significant value, and these are usually controlled by some elite powers.
Most typically, these would be the top academies.
The Secret Realm resources of these academies are generally only open to their own students, except occasionally during exchanges between institutions.
As for other outsiders, it's basically quite unlikely for them to enter these Secret Realms.
But obviously, as long as there is a society, privilege will never be absent.
