Devektra, a famous Garde singer, uses this legacy in conjunction with her Light Manipulation to give her audience different sensations during her performances. Her clever way of using the two legacies makes her music unique.
During the Mogadorian Invasion of Lorien, Devektra used her manipulation of Sound to defend Sandor and Number Nine from a Mogadorian. The sound was so loud that the Soldier reeled backwards and dropped his sword as his face showed a horrified mask of pain. The attack gave Sandor a chance to pick up the sword and cut the Soldiers head off.
Has all Legacies.
Nigel developed this as one of his first Legacies. With it, he has been able to amplify his voice to deafening volumes and negate sound in a localized field.
