No one except him, Llyord Riddle, brother of Tom Marvolo Riddle and the most powerful wizard next to Albus Dumbledore and Lord Voldemort, knew about the next prophecy. Right at the start of the Battle of Hogwarts a prophecy was made, Llyord never meant to see it happen but he did. He just wanted to see his brother defeat Harry Potter. So he turned invisible and went inside Hogwarts to see the fight, but he noticed Sybill Trelawney walking, then the prophecy was made, in a haunting voice, she said"The Dark lord will fall but the brother will raise. He must get revenge, so he will become the new Dark Lord, he will be the greatest dark wizard ever seen before, yet one will oppose him, that one will have the power to defeat the new Dark Lord. The new Dark Lord must destroy the opposing one and truly become the most powerful dark wizard". Then Sybill Trelawney just kept on walking like the prophecy never happened. Llyord looked over the tower to see his brother getting vanquished by the boy. Llyord was furious, it wasn't suppose to happen this way, the boy was suppose die, not Tom.He roared with a tone that would even make Severus Snape nervous "Harry Potter will die and I will get my revenge, mark my words, for I am the brother of Tom Marvolo Riddle" and with that Llyord disapparated to his Palace.
