Mages are active understanding classes. Being a class that “understands” their aspect, they cannot directly change or affect their aspect in any way. However, they have immense power both through their active knowledge on their aspect and through the aspect itself, as well as its opposite. A Mage’s inverse is an Heir, a passive changing class. The way a Mage or Seer operates is through the power of its inverse: they understand the shape and form, or “mold,” of their aspect, and change the opposing aspect to fit the ramifications of this mold. This is how Mages and Seers can do incredible things with their opposing aspect while providing a remarkable understanding of their own.
Space is one of the two cardinal aspects. Along with Time it makes up everything in the physical plane, and the duality of creation and destruction. While Time is more inclined towards destruction and the abstract, Space is more about creation and practical things. Space represents everything spacial and physical in reality, making Space players good with what is there and tangible. Space itself is crucial in a session due to the breeding of the Genesis Frog, a duty that always falls on the Space player because of Space’s association with universes and creation. Space also ties in with creativity and resources, aesthetics and fashion, and practicality and form.
Mage of Space is the active class of understanding space. A Mage of Space would have an incredible knowledge of the space they are occupying, practically an encyclopedic awareness at any time of where all bodies, both celestial and living, are residing. They’d likely also have a great awareness of where these objects will move, though not necessarily how long it’ll take them to move there. That’s not incredibly relevant, however, as the inverse is Heir of Time, meaning they are capable of passively influencing and changing the flow of time to fit their information.
