When a person had slain the Ender Dragon the purple beams of light try to touch the player injecting the person with the Dragon's DNA. The person, unaware of what had happened, goes into the portal, not forgeting to get the dragon egg. When the person reaches home, it is starting to get dark the player goes into his bed. When the night is over he gets up, still unaware of the infection. The person does not know hat had happened to him that night, growing dragon horns and claw-like fingers.
