Astronomical — the signature ability of Sirius Lycaon. In this world, abilities are tied to the knowledge of each individual, and you can push them to their limit depending on how much you study and how much affinity you have with them. In Sirius's case, reality itself was something that awakened his curiosity, and from that curiosity he developed these three spells, which serve as the foundation for all the others he has mastered. While records of them do exist, they are useless without knowledge of the original formula, as what is documented here is merely the result — not the equations behind it. Attempting to use them without prior understanding can be catastrophic for the user and everything around them.
