Also, I do want to clarify a few things for everyone, just in case it wasn't apparent in the intro post or the subsequent posts - while different planes may have different cultures and technologies, on Earth, it is modern day, let's say August of 2023 when they first go to Orientation. As stated in the intro post, the time of day at the Academy within it's sub-planar realm is synced with GMT (Greenwich Mean Time) at the Royal Observatory in London. As for the overall structure of this reality, here is an image that will help, though I'll define it further when the main thread goes up:

Think of this bubble as representing the Aetherscape, and think of the Elemental Planes as if it was cut into four quarter wedges like an apple. The galaxy swirling inside represents the many different Mortal Planes, which are like parallel universes co-existing. They are all spinning so fast that the speed in inconceivable to Mortals and from a quantum perspective, are technically sitting inside all four Elemental Planes at the same time. That motion is what keeps the balance between the elements in the Mortal Planes, and why all Magi are attuned to one of the Elemental Planes. The light in the center represents something I haven't discussed yet, so we'll just call it the Celestial Spark, a place where new souls pop into existence right before being born into a physical body. This cloud of divine light surrounds a black hole in the center of the Aetherscape that represents the Infernal Abyss, and together they act as the anchor for the Aetherscape and work with the Elemental Planes to maintain balance. The black space beyond is the Cosmic Void.
