I LOVE THE EVERLOVING SHIT out of The Immortal Game. And you're right, bladecasting is hardcore Lunar magic. Bladecasting, at least at low levels, is essentially finely-controlled multi-target telekinesis. The Blade can be "assembled" and wielded as a single unit for maximum damage and magic-construct dispersion, or "disassembled" and used for various feint, multi-pronged, and "cloud" style attacks. At higher levels (casting a blade from nothing) bladecasting utilizes a form of subspace distortion and matter inversion to summon a physical blade from the quantum-magical soup that is The Dreaming (Dangerous Business reference). Blades summoned this way are even more versatile than normal bladecaster blades, due to their infinitely higher "resolution" (number of segments). It should also be noted that the summoning and wielding of a mageblade is an art, learned through trial and error and perfected through rigorous practice. Lunar magic all the way.Also are you trying to go all Attack on Titan on the use of bladecasting within the MLP universe?And now for my understanding of the Equestria Total Magic System (as I have just now decided to call it).[1] Each species has its own, mostly unique, source of magic and school of magic. All creatures can to some extent convert ingested food into magical energy, athough some have more direct or efficient means than others.[2] Ponies in general have the Solar/Lunar model of magical manipulation and construction, which I wrote about earlier. As for their source of magic, Pegasi can utilize atmospheric electrical, thermal, or pressure disturbances to catalyze basic subatomic-interaction/manipulation effects, such as cloud walking, lightning casting, and the art of storm creation. Earth Ponies can draw power from the earth, in the form of thermal or ley (magical) energy, to fuel their immensely powerful and long-lasting geological effects. Unicorns are actually the least blessed of the three races in terms of energy absorbtion – they have no natural external power source other than food intake, so if they wish to harness additional energy they must engineer mana intakes and manipulation systems directly into their spells. However because of this, Unicorn magic is the most sophisticated and versatile school of magic in the world.[3] This is where it gets fun. Dragons are powered by a self-sustaining miniaturized fusion reaction which takes place in a special magical construct within the body. Because of this, Dragons can maintain their magic on nothing more than hydrogen (by drinking and converting water), are gifted with immense power and have incredible longevity. The oldest dragons do not even need food, dreaming their days away underground, supplied with water from the subterranean aquifiers, their internal fusion providing all the energy they need. Dragons shape spells using "Incantations" (A precise arrangement of meaningful words in a harmonious pattern), driving their magic through a complex emotional system that is utterly incomprehensible to other races. Thus Dragons are the great poets of the world.[4] Changelings have no ability to convert food intake into magical energy, and must drain magical energy from another being directly (ley or "raw" magic being incompatible with most living beings' internal magic systems). Furthermore, individuals undergoing extremes of emotion have higher levels of stored magical energy, making the infatuated, despondent, or heartbroken extremely tempting targets.[5] Deer (of which there are three known but only two surviving races) can absorb magical energy directly from almost any natural source not under direct control of another consciousness. They also are blessed with many-tined antlers, magical constructs capable of channeling immense quantities of power in an instant, but which lack "accuracy", leading to the rapid breakdown of any Deerish spell not under active maintenance. The Deer overcame this shortcoming by designing and fashioning crystalline structures capable of channeling and guiding magical energy in a set pattern for theoretically unlimited periods of time. (Dangerous Business reference.) Thus the Deer are the great builders and inventors of the world.SO, how does Dark Magic play into all of this? It is simple. Dark Magic is in theory just as accessible to a magical individual as any type of "light" magic. It is not more complicated, more difficult, or uniquely specialized in any way. "Lunar" magic can easily stray into mentally-invasive magic, magic that plays with the soul, and even magic which reanimates the dead. Likewise, "Solar" magic can easily stray into emotionally-manipulative magic, magic which affects the mind, and even magic which attempts to alter the past, the future, or the nature of the universe. Good examples of "dark" magic include the Want It-Need It Spell, Sombra's memory and mental-torture spells, and the spell that powers the Alicorn Amulet. However, in a land as magically rich as Equestria, with all its magical history, there are innumerable cultural taboos and religious, professional, and legislative restrictions on the practicing of Dark Magic. While it is possible to practice the Dark Arts, and undoubtedly there are cults and organizations that do, doing so bucks millenia of tradition, folklore, mythology, morality, and even instinct, and in most countries is punishable to the fullest extent permitted by law.It's like 2 in the morning! I have no idea what I'm writing! Hooray for on-the-spot headcanon categorization and systematization!
