Merlin asked many things of Harry's life, and for once Harry didn't hold back. He told him everything. It seemed they were there for hours when Harry came to the sudden realization the others were waiting.
Harry looked at the Old man; he still hadn't even asked his name. "Sir, There are people waiting outside, I'm sure they are worried by now. We should head out."
Merlin Looked at him and waved his right hand. "Not to worry my son, now one more thing before we go meet your friends."
Merlin brought out his staff, And cast a spell over Harry and he glowed golden except for his forehead Which had a black tinge to it. Merlin placed the tip of his staff against Harry's scar. The pain that ran through Harry was excruciating. Then it was gone, it was as if a weight Harry didn't know he was carrying was lifted from him. He felt his Magic sing in his veins. He looked at Merlin with an awe so complete that it scared him.
"What did you DO?" asked Harry.
Merlin Looked at the boy. "You my son had a piece of an evil soul that had attached it self to you. I removed it. It was using your Magic to survive. I also removed the bindings on your magical core and your mind. With those bindings You were not able to learn as well as you should. We may go meet those that await us now."
Harry was amazed at what happened in so short a time. "What is your Name Sir, if I may ask?"
"Why it is Merlin Emery's Of course."
Standing by the Lake as Harry disappeared into a solid stone the others waited. Hermione and Kreacher continued to explain everything to Sirius, Time travel, the experiences of their previous lives, How they came to be married at the age of eleven. Kreacher explained he had the memories of all this at the Black family home, and hoped Sirius would approve the changes.
Harry emerged from the Stone with Merlin behind him. He stood before the assembled group with a smile. "Hermione, Sirius, Kreacher, I'd Like you to meet our new teacher…..Merlin Emery's!"
To say they were all with out words was not even close. To even know this man was still alive was beyond any expectations. Hermione was the first to break. "It's an honor to meet you sir." Merlin looked at Hermione. "My dear the honor is mine, young Harry told me of your adventures and that you are the smartest witch of the age, he some how did not tell me of your beauty which is a sight for these old eyes."
Hermione was blushing when he finished. Harry Looked at Merlin. "No Flirting with my wife old man." Merlin laughed. "At my age flirting is all I have left."
Sirius, Harry, And Merlin were laughing while Hermione looked scandalized. Merlin then continued. "From what Harry tells me it has been a very long time since I walked among the people, and I hunger do you think we could find a place to sup and talk. It would seem I have new apprentices."
"Harry has told me of the battles you fought in the future; may I tell you why I found you Foolish in those battles?"
Harry Looked at Merlin. "Foolish?"
Merlin looked back at him. "You fought the same wizards and witches many times unnecessarily. You look at all killing as murder.
Killing in battle is not murder it is survival. If you kill in battle, you are fighting the dark and extinguish its minions. The difference is when the battle ends the light mourns all the deaths, while Dark rejoices in your deaths and theirs. We will only rejoice that the battle has finished and we have one, while we honor the victorious dead."
Hermione Looked at him in horror. "You mean is alright to kill?"
Merlin smiled. "To fight a battle once and win, is intelligent and minimizes deaths, To fight it over and over again allows your enemy to gain strength while you diminish your own, if they know you will not kill they know you will eventually stand in fear as you are the last to fight. They know you are to foolish to win, so they play the game knowing they will ultimately win in the end."
While they were talking, Kreacher popped away to the kitchens at Hogwarts and returned with a veritable feast.
Merlin conjured a table chairs and elegant plates with no silverware, and began eating with his hands. Hermione instantly conjured knives forks and spoons, and began to eat as Merlin looked on.
"What are these that you use to eat? I have never seen such before save fore the knife."
Hermione looked at him as if how could you not know until she realized that the utensils they used had not yet been invented in Merlin's time.
Hermione showed there use and gave them over to Merlin. He examined them closely. "Such simplicity" Said Merlin. "And yet to make large kitchen implements small and to eat with them. I have as much to learn from you as you from me."
"Harry, Now that we have finished our fine meal provided by our friend Kreacher, will you go back to the cave, gather the moss and mushrooms there. We have a potion to brew. You have told me of a scourge created by my ex-wife Morgana. This must be cured, The mushrooms and moss found within the cave only grow there in all the world. They are the elements of the werewolf cure. Also bring samples of the soil so we may grow more."
Harry did as instructed, in side the cave he found three large baskets old and in disrepair. He cast the repairo Charm on them and they reformed. He filled each basket separately and levitated them out of the cave. Then led them all back to Hogwarts.
