The general evolution of magical technology in Aesca. Not shown: other forms of magic that aren't relevant or that I couldn't fit into this super quick chart, such as Fourth Age technomancy, or magic that is quickly covered under a larger, more encompassing titles (wonder-working covers almost everything you can do with fossils, for example). I will do a more detailed chart in the future.
Magical practices diverge culturally, individually based on spirits with whom a bargain is made, or just happen when a confluence of circumstances makes them work. Talents, for example, are inborn. Study of how they work in combination with wonder-working generally leads to a species-specific power and is a required step on the path to becoming a race.
Blue - Extremely common. Everyone has heard of this and it is in practice everywhere to the point where it is utilized in most religions, cultures, and technologies.
Red - Extinct. There is no longer any culture that uses this because the materials to make it work no longer exist, because the culture that practiced any form of it is extinct, or because the bargain that created it has expired.
Black - Somewhat common. People generally know that these are things, but don't know much of anything about them. The difference between a "shaman" and a "wonder-worker" to the public, for example, is practically nothing (the truth is more subtle and complex, shamanism is guiding between the living and the dead, while wonder-working has none of that context). Most cultures have a form of these magic types in some way, other than Biomancy, which is only practiced to any degree in one hemisphere.
Purple - Extremely rare. Either possessed by a small culture or subculture, requiring special circumstances to even be used, or utilized only while actively traveling songlines but not at Destinations.
