Nightlight, bright light,
Nightlight is an enigmatic immortal boy that was once the Man in the Moon's bodyguard until he helped seal Pitch away the first time. Since his and Pitch's reawakening, he's mostly enjoyed wandering the earth in addition to bringing his own abilities to the fight. He becomes Katherine's closest friend.
Being a boy of pure light energy, Nightlight is very bright, easily shining through any darkness you throw at him.
He is a young boy with a friendly face, white hair, and pale green eyes. His attire appears to be armor.
Nightlight is a little shy, but extremely friendly. He is very curious and playful, but is also very loyal to his friends.
Nightlight was Man in the Moon's bodyguard when he was a baby. Every night, he would sprinkle Dreamsand on the baby and watch over his dreams for Nightlight never sleeps. Before Man in the Moon's parents were going to face Pitch, they had Nightlight take an oath and protect their son within the Moon Clipper. During the battle, Man in the Moon was so scared, that he cried and Nightlight caught the tear and repeated the oath and the tear hardened into a diamond dagger. After bidding good-bye to his ward and taking the dagger, he entered the battle. At this time, Tsar and Tsarina Lunar were captured and Pitch almost won until Nightlight went and stabbed Pitch in the heart with the diamond dagger and caused an explosion brighter than twenty suns. Pitch fell into a dark cave and Nightlight was trapped in his cold heart. He remained there until a moonbeam accidentally entered the dagger awakened him and unintentionally Pitch as well. When Nightlight was freed, he had no memory of who he was and tied his dagger on stick and created a staff. When he saw the sleeping in a nearby village, an old memory appeared and faded in his mind which left confused. However, he was free and traveled until he saved the children of Santoff Claussen from an fearling attack. From time to time, Nightlight would travel the world and play tag with the moonbeams and also get curious about the people on Earth.
