When all the candidates had gone through their tasks and get their eggs, they were reunited, and told they would have two months to prepare for the second task. The golden egg contained a capital clue for their preparation. After the reunion, Harry and Ed crossed the park together and went back to the common room, where a surprise was waiting for them.

"Ladies and gentlemen!" Fred amplified voice started. "Please welcome the two champions of the day: Harry Potter, and Edmund Peeves!"

And the room exploded in applauses and cheers. The loudest applauses were Ron's, who had finally made peace with Harry, but the loudest cheers came from the Narnians and were for Ed. The twins came closer to the young man.

"Good game, Edmund Peeves. Nice trick! Charlie's never tired of praising you!"

"As for Hagrid, he's delighted you didn't cast a spell on his beloved Norberta."

"Norberta?"

"Hagrid had a dragon egg, when I was in first year." Harry explained as he had followed the conversation. "He called the dragon Norbert, and we had to convince him that it was not a good idea to keep a dragon in a wooden cabin."

"Charlie came to get Norbert and brought it to Romania." Ron added. "It was a real heartbreak for Hagrid. He's always loved giant scary animals. In addition to the dragon, he has a huge dog called Fang, a three-headed dog he calls Fluffy, and a giant spider... Horrible!"

As he said that, he shivered. And the party went on. It took the joined efforts of both Professor MacGonagall and General Glozelle to send everyone to his own dormitory.

During the night, Ed thought about what Hermione had whispered to his ear before her memory was erased. Dragon eggs hatch under water. Of course, it didn't make any sense. On the contrary, dragon eggs needed much more heat that any other kind of egg. But maybe a fake one... it was worth a try. When the sun rose, he carefully observed the golden egg. There were markings all over the shell, which he studied attentively. The drawings comforted him in his idea. At the top of the egg was a locket. He understood that, once under water, he would need to open it. He decided he had no time to waste, and headed to the requirement room, where a warm water basin was waiting for him. He undressed, entered the basin, immersed himself completely, and opened the egg. He then heard a voice, reciting a poem.

" Come seek us where our voices sound,

We cannot sing above the ground,

And while you're searching ponder this;

We've taken what you'll sorely miss,

An hour long you'll have to look,

And to recover what we took,

But past an hour, the prospect's black,

Too late, it's gone, it won't come back."

After listening to the message a few more times, he got out of the water. He doubted the threat of the last two verses would be executed, but it didn't stop him from worrying. It meant he would have to stay under water for an entire hour, maybe more. He had to find a way. He went back to find Hermione, and she suggested they should go the library. That's where he spent most of his time for the next two days, in her company, searching in the books, looking for an answer. He was the one who found it.

"Diver's potion!" He exclaimed.

He showed Hermione the book.

"It's a complicated potion." she said. "Do you feel up to it?"

"It's like a cooking recipe. I liked to cook, from time to time, in Narnia, and I was quite good. If I follow the recipe, I should be alright. Now the question is: how do I get the ingredients and the material?"

"Glozelle will get you access to Snape's potion room."

They borrowed the book, and joined the other Narnians.
