Light Manipulation is a Legacy that gives the user to manipulate light waves for a range of different effects, often dazzling, hyponotic light displays.
Ella's father was said to have this Legacy. He was able to use it to darken the surroundings around an enemy and make it hard for them to see, a tactical advantage.
In courtship of Ella's mother, Erina, Raylan would stand in the courtyard, while she would fly with his Chimæra, and would use his Legacy to change the colour of her lightning strikes. Raylan and Erina soon married and conceived a child, Ella.
Elders with the title of Pittacus Lore are able to replicate any Legacy they have seen using Ximic. This including Light Manipulation as well.
Mentioned in Raising Monsters, dead by a parasite in her head for an experience.
