'I've never seen a spatial ring designed in this way. The level of Space Inheritance needed would have to be at the Dominion Realm at a minimum, and that's a conservative estimate.'
Ailsa quickly agreed. 'A rare Spatial Sprite of the Inanis Clan might not be able to do this without years of training. Building a space capable of sustaining the opening of another space takes a level of skill beyond normal means…'
This sort of field of study was incredible in depth. Though Ailsa explained in so few words, the reality was far more complex than this.
Normal spatial rings could use the plane it current exists on as an anchor. However, even they have a lifespan. Over time, the inner space of a spatial ring will inevitably collapse as its ability to connect to a stabilizing plane wanes.
