[ WP ] Write a story that starts like a Christmas tale but slowly becomes a Cosmic Horror story .

The North Pole laid quiet as winter's grasp unwound, 
 
 Santa, the elves, and the reindeer slept sound, 
 
 The Earth still stood rotund, spherical and round, 
 
 But not *all* was as it seemed - there was **mystery** to be found! 
 
 For here came a demon, looking to posses, 
 
 A cute little reindeer who felt outcast and oppressed, 
 
 To grant his wishes of alleviated stress, 
 
 And to prove to the others that he was n't such a mess. 
 
 So the demon awoke the young buck to answer his prayers, 
 
 A startled Rudolph looked up, `` Who is out there?!'' 
 
 `` It is me, young one, speak my name if you dare...'' 
 
 `` I dreamed of you, Beezlebub, you gave me quite a scare!'' 
 
 With a whisk, and a flick, and a wasp of his wrist, 
 
 The demon appeared humbly-a sight not to be missed. 
 
 For the ground erupted in red fire, flames danced and kissed, 
 
 Joyous is the naivety of a poor reindeer amiss. 
 
 Rudolph seemed startled, but calm, as the demon took reign, 
 
 Slowly his gaze thickened, unlike that of his brain, 
 
 For the stud's head began leaking through his ears like rain, 
 
 Until the only thoughts left were that of a stain. 
 
 So Beezlebub awoke all the other reindeer, 
 
 He made sure to scream loud and proud and clear, 
 
 Sliding his claws across their throats from ear to ear, 
 
 He slaughtered them all as they bled out in fear. 
 
 He killed Dasher and Dancer and Prancer and Vixen! 
 
 Comet and Cupid and Donner and Blitzen! 
 
 The demon licked his lips as his kills were now christened, 
 
 The bullies from the North who failed to listen.
