Walled Gardens

A walled garden is a pockett dimension lodged in the membrane of the reality. Sort of like little bubbles in a hollow sphere of ice. There are uncountable trillions, but almost all are empty A walled garden is when one of those lodged in pocket dimensions is used to contain an entire self-contained eco-system, which is usually utopian in nature. They are often used to preserve a species or set of species, or even a culture against Purges. Walled Gardens cannot be reached by Purges as they sit outside of main reality. Walled gardens can only be acessed by Realm Masters, who are the only beings capable of passing through Exotic Matter, which is what the boundaries between reality and the Continuo are of. As Realm Masters can't pass the Continuo, they are limited to this reality. Realm Masters can also forge an Iron Key, which is an arm-length raught-iron key with a gothic style. Each Iron Key in existence pertains to a certain walled garden, which can only be accessed by it, not even by another Realm Master. Even beings that are not Realm Masters can use one, which is why they are so useful.
