• Sigurd suppresses his aura with sealing techniques and waits until night to investigate how moonlight and starlight function compared with sunlight.

• Tokiju classifies these celestial sources as “Heavenly Light.” In contrast, fire, electricity, and other terrestrial forms of light are called “Earth Light.”
