Here's a storyrant thingy that I wrote because I needed to put something on this. Disclaimer: I don't own Rise of the Guardians.
Pitch Black, Pitch Black soul as dark as night. Corrupted, destroyed beyond repair… or so the thought. Pitch Black, Pitch Black used to be a solder Kosmos Pitchner was his name tackled may enemies. Until the darkness called his name. Fearling took over his vary being nightmares at his finger tips. It crushed those who once knew his name. But whoever knew the Nightmare king was once and few between. It never stopped that cold hearted soul who could never love. Never hope. Never dream. What could become of this monster? He asked himself so. But then a boy came to his life. His job to shepered snow. They worked to learn what they could not know. What they wished to learn how. Then the Nightmare King lost his boy and would never open up again.
Lame story. It's the worst story ever! Sorry it's late.
