Lightweaving is a magical ability found in the Cosmere, a universe created by author Brandon Sanderson. It allows users, known as Lightweavers, to manipulate light and create illusions. This power can be used to craft intricate images, change appearances, or even create solid objects made of light. The practice of Lightweaving involves drawing upon the Spiritual Realm and using specific colors and patterns to shape the light. Lightweavers often rely on their creativity and imagination, making this ability not only powerful but also an art form. The skill is closely tied to the Nahel Bond with a spren, a magical being that grants the user their powers.
