Light (Night Watch)
From Tardis Wiki, the free Doctor Who reference
Some members of the population of a planet made of sapphire became blue lights after they were devoured by the Night Sun. They were stuck alone with the Night Sun and targeted the lonely, giving them waking nightmares.
When the Night Sun came to Cardiff through the Rift, the lights targeted St John Colchester, Yvonne Hartman and Tyler Steele. God sent Orr to care for the people of the city and to collect the lights, bringing them together. (AUDIO: Night Watch)
