Celestia's sadness

Cinnamon and Neptune were sleeping peacefully in their huge cabin and were warm and as happy as can be,all cozy in this dark and cold winter night as a dark figure sdescends from the darkness as his blood red eyes penetrate the cabin's surrounding scanning the house as he sees the last light of the cabin turn off. Setting a hoof on the grass which has a heavy layer of dew as his horn and wings glow bright gold as if he is a glitter bomb spewing gold dust as he unlocks the door and slips in letting a cold draft into the house stirring Cinnamon. As he laughs bathing the house in a light transforming Neptune and Cinnamon into foals as neptune hobbles over to cinnamon and puts him on her back and hobbles over to their grandfather as he laughs and looks down on his grandchildren and pulls out a carving knife ready to slaughter both of them...
