Photokinesis

Photokinesis is the ability of a power source to generate and emit light. In speculative fiction, this is usually represented as a super-power or a mystical ability. On the HBO television series True Blood, members of the Fae race have the ability to project light. This light can be used to repel the advances of a vampire, and is the Fae's primary defense against the undead. Fae halflings also possess this ability, including Sookie Stackhouse. Sookie and other members of the Fae combined their light in an effort to fight off a vampire named Russell Edgington. Due to Russell's age however, and the fact that he was super-juiced on Lilith blood, the photokinetic effect did not weaken him, but merely whetted his appetite.
