Fire Emblem: The Age of Legend
Though it is somewhat mysterious, magic is generally seen as the altering of the normal physical world through the application of willpower and Aegir.
Though some think otherwise (which is often seen as Heresy or simple ignorance), from a scholar’s perspective magic is not any sort of force in its own right. Rather, it is simply a property of Aegir. Magic therefore has always been possible for the strong and willful, but according to some accounts was first really demonstrated and used deliberately by Henrekta somewhere around 1A 120 or so.
The only real difference between different sorts of magic then is whose Aegir is being used and what it is being used to do. According to common definitions, magic can thus be divided as follows:
1) Pure Magic – The oldest sort, this is the use of one’s own tremendous Aegir to reshape reality as one sees fit. It is this which Henrekta would have developed. This is impossible for ordinary people to cause any sort of meaningful effect with, that required the overwhelming power of the First Generations.
2) Imbuing – Perhaps just another aspect of Pure Magic, this is imparting Aegir into something else, generally with some specific purpose in mind. The most obvious example are the countless healing Staves made and sold by the churches of Fundin. Within these easily portable and useful rods is stored a great deal of collected Aegir bound so that it can only be by imparting it to the injured to heal their wounds.
3) Dark Magic – The oldest sort which the Fourth Generation can wield and insistently called “Elder Magic” by its wielders. This and all others that follow it could be argued are simply Pure Magic exercised using one’s own will but someone else’s Aegir. In this case it is Grimholt, a most sinister and untrustworthy god. According to legend, Dark Magic originated when Sekeriah bested Grimholt in a fight and spared his life in exchange for the god granting his power to any who demanded it. This might have happened somewhere around 1A 500. Dark Magic is can be very powerful, but is as strange and dangerous as its creator. To learn to use it safely requires many years of study and careful parsing of every sentence of every spell.
4) Anima Magic – Similar to Dark Magic, this is commonly held to originate from Ehrholt’s power after a similar deal was extracted from him perhaps around 1A 570. It is less outright malevolent toward its wielder but still dangerous in unskilled hands and not always predictable.
5) Light Magic – Similar to Dark Magic, this is commonly held to originate from Skaihalth’s power after either she was forced into a similar deal or granted it somewhat voluntarily. Reflecting her nature, it is intuitive and easy to learn and wield and a misstep is more likely to aid than slay the spellcaster.
6) Profane Magic – Sometimes Dark Magic is lumped into this category by the ignorant and fearful, this is generally defined as magic stemming from worship of one or more Gods rather than from one’s own power or one of the deals struck by Sekeriah. It is the province of heretics and their ilk.
