Saev holds a low horse stance with one palm out and one fist at the hip in an ice valley, under aurora.
Saev sinks into horse stance with the lead palm guarding the chest and the other fist drawn back at the hip. The feet press into the ice to stay rooted. Rooting uses friction and gravity to hold ground, which is mastery of the physical laws.
Vaelis is invented. On Earth, auroral green and red come from oxygen and blue to pink from nitrogen, when fast particles make these gases glow.
Practice
Stand in horse stance and press your feet into the floor for ten breaths.
