Magic

There are three sides to the magic of Aetherline.
The magic of the soul is thematically associated with the colours red and black and the elements of fire and darkness. It's fueled by strong emotion and best at accomplishing immediate, dramatic effects, especially but not exclusively destructive ones. When acting autonomously it tends to act in accordance with the user's most strongly felt desires, often something like 'protect myself and my loved ones' or 'destroy my enemies'.
The magic of the body is thematically associated with the colours green and yellow and the elements of earth/life and light. It's commonly accessed through meditation or other ways of being very in tune with your body and senses, and its strengths are healing, sensing, and passive effects. When acting autonomously it tends to offer the user subtle insights and intuitive hints that help them achieve their goals.
The magic of the mind is thematically associated with the colours blue and white and the elements of water and air. It's the most intellectualized form of magic, and relies a lot on willpower, concentration, and working memory. It's most often used for everyday applications of telekinesis/telepathy and for building magical artifacts. It almost never acts autonomously.
