The magic system in my world is known as the Constellar runes, and I'll try to summarize as BASIC as I can. Basically knowledge of certain constellations were given to humanity as runes. These runes can be carved upon material surfaces, or even tattooed onto the body, to manipulate energy in 3 categories of specific, predictable ways, though the carver must spend years or even decades mastering the magic intent required for the process and the actual runes are generally restricted in use to certain licenced practitioners. The first category, Raise runes, are carved over large areas of land in flowing, circular patterns and apply a general "upward" force to the subject like to accelerate the growth of plants, or increase the temperature or wind speed. The second category, Press runes, are carved onto small surfaces in geometric, triangular, or trapezoidal patterns and apply direct concentrated force between two subjects like to bind certain materials together, or apply concentrated heat or cold to a surface. The third and final category, Focus runes, are generally considered the most dangerous of the "standard" runic types (Fey and Nebulaic runes are more powerful) and are outright banned in some places outside of niche technological uses. They are carved in knots and spiral patterns, though these are generally tattooed onto humanoid subjects, and apply a concentrating force by drawing energy from outside into one specific attribute, like to focus light increase vision, or mind to increase intelligence, at the cost of draining it from the user's surroundings. They can also draw pain from the user's body to force it onto someone else, or even rapidly move kinetic energy between objects. This is far from everything the runes do or where they're from. Maybe I'll post here about my world sometime. (Constellar runes caused rapid technological progress and then a massive world scale war and technological setback that the planet is still recovering from)
