What if a chocolate frog could change everything

Harry and Minerva found that nothing had changed since they had first visited Santa's Workshop ten years ago. However, it was even more fun showing their children the place and seeing how happy Santa Paws was to see his siblings and parents after such a long time.

In the evening of Christmas Day, Santa took Santa Paws and several of his siblings out onto the grounds and around the building, inviting the family to join them. Behind the building were too enormous Christmas trees, beautifully decorated and illuminated, and Santa instructed the dogs to sit in a circle between the trees.

Only then did Harry noticed that a huge ice crystal was hanging from a rope that was connected to the tips of the trees. The crystal magically connected to Santa Paws' collar, which flashed bright red, before the dog let out a squeal and dashed away, jumping at Harry.

Overwhelmed by the weight against his chest, Harry gave the dog's face a close look – only to realise that he looked much younger.

=I'm a puppy again, even if I'm not so small anymore and I have all my memories, but I'm only few months old. In ten years, we'll have to come back, so that I'll never have to leave you because of old age,= he informed Harry, who gently cradled his familiar close.

"That's the best Christmas present ever," he replied, while Minerva explained the matter to their children in a quiet voice.

Shortly after their Christmas holiday at the North Pole, Arcturus retired from his active work with the Unspeakables due to his high age. Still living in the retirement home at Hogwarts with his wife Theresa, he worked just a few hours per week in the Chocolate Frog office, which was a not well-known part of the Ministry of Magic.

One of his first tasks was to update older chocolate frog cards, and – looking at a certain card of Harry Potter – he realised that there were wizards who had done too much good for everything to fit on one card. Enlisting his sister Dorea's assistance, he worked out a new system for chocolate frog cards. From that time onwards, there were normal wizard's cards, silver cards, gold cards and platinum cards.

One day, the Daily Prophet announced the new classification of chocolate frog cards, which depended on how many entries the respective card held.

'Currently, there are two platinum cards,' the Daily Prophet recited, 'one for Merlin and one for Harry Hogwarts-Potter. However, they are very rare, and only three of each of them exist.'

"Mum," eleven-year-old Theresa Potter enquired, "do you know what that means?"

"Yes dear, I'll show you after breakfast," Minerva replied, smiling.

As soon as breakfast was over and Harry and the other teachers had gone to make last-minute preparations for the new school year that was going to commence on the following day, Minerva took Theresa into her office.

"Your Daddy is a wonderful man – in case you haven't noticed," she said, smiling.

"I know that, Mum, and I can't wait to become a student tomorrow," Theresa replied in apparent excitement.

Minerva let out a deep sigh. "He has two chocolate frog cards," she explained, handing her daughter the new, platinum edition.

'Harry Hogwarts-Potter, time-traveller, owner of Hogwarts, married to headmistress Minerva Hogwarts-McGonagall, father of two children, Potions Master and Potions professor at Hogwarts, Unspeakable, head of the Wizengamot, receiver of the Order of Merlin first class once for vanquishing the Dark Lord, a second time for inventing the wolvescure after a long-lost recipe of Salazar Slytherin, and a third time for giving the Squibs a second chance at magic, visitor of Santa's Workshop together with his wife on the invitation of Queen Elizabeth II. Owner of one of Santa's sacred dogs as well as a phoenix familiar.'

"Oh Merlin," Theresa blurted out, eyeing the beautiful card, which held a photograph of her father, who kept changing between his human and his Animagi forms, in apparent amazement.

"Mum, will you teach me to become an Animagus, please?" she enquired, giving her mother a pleading look.

"We will," Minerva promised. "I'll speak with Dad about it tonight."

"Thanks," Theresa replied, happily.

"Do you want to see the other card as well?" Minerva enquired and – upon her daughter's nod – handed her a much older and simpler card. "This was the beginning of our new time-line," she added.

Together with Lily and Amelia, who had followed their conversation, she smiled, as her daughter engrossed herself in reading the card from the chocolate frog that had been able to change everything.
