Merlin and Arthur approached what Arthur could only describe as a castle. He was in awe by its size. Seeing him Merlin told him that the building was known as Edo Castle and it was home to the current leader of Japan, the Emperor.
"Why are we going there?" Arthur asked.
"Because that is where Morgan is hiding. Like me, she is also a fox spirit. She has used her magic to trick the Emperor into taking her as his wife. Then she used her magic to create the grand building you see before you," Merlin Answered.
"She's a Fox? How old is she? And I think it's time you told me what she stole from you" Arthur asserted, refusing to continue until he knew more about Merlin's mortal apparent mortal enemy.
"Yes, she is a fox. Before she trapped me, she was only alive for 300 years, but by now she should be around 900 years old" Merlin told him.
And before Merlin could continue, Arthur interrupted. "Wait, she only had three tails when she trapped you? Did you have nine at the time? How was she able to overpower you?" Arthur wondered. Until now he was under the impression that a fox's age and number of tails determined how powerful it was. He was dumbfounded how a three-tails could over power a nine-tails.
"Yes. I let my guard down with her. She was my student. I was training her in magic, what it meant to be a fox-spirit and how to stay alive. However, she was ambitious. She stole he source of my, of all fox spirits power. It is the source of our power and our immortality, my fox-fire. It is the elixir of life; the closest way I can describe it how you'd understand is our Holy Grail. Once she stole it from me, she gained enough power to curse me. It is my fox-fire that we are here to recover."
“Could you not just create another elixir?”
“Afraid not. A fox-spirit’s fox-fire is the equivalent to a human soul. We only have one our entire lives that we can naturally create. We spend our entire lives training the mind and body to strengthen our spirits thus empowering the fox-fire, crafting the elixir of life. Without it we are mortal. Yes, we still have our magic, but our lifespan only is that of a mortal being. But all that aside, if we do not defeat Morgan, her ambition will lead her to attempting to take over the world. And possibly, she will continue to mess with the flow of time. She already pulled Edo Castle in from the future. It was not supposed to have been created for another couple of hundred years. She must be destroyed, and my power reclaimed.” Merlin told Arthur.
"I’m not sure I completely understand the aspect of messing with time, nor am I going to question how you, or she knows about the future. What is important to me is I promised you I would help you defeat her and get back what she stole. Let's go get your fox-fire!" Arthur proclaimed.
And our heroes made their way closer to Edo Castle, and the battle that awaits them.

Author's Note: I decided to make Morgan Merlin's student, because in many stories that's how she started out. She had a gift for magic and Merlin saw it so Merlin decided to train her. And just like in my story, she betrayed him. Similarly, there are even stories where she did seal him away from the world which I only just remembered. I initially wanted to have the castle be Edo Dastle itself, but the timeline of the Shogun in Edo does not match up with when it is suspected Arthur existed. Making Morgan a fox became a simple decision once I decided to make her Merlin's student, and it worked well with her tricking someone since in popular culture and in myths foxes are often portrayed as tricksters. I chose to give her a small number of tails to describe the difference in Age between Morgan and Merlin, and her being nine-tailed now to give a rough estimate at how long Merlin was trapped in the sword. This is where I combine the story of Fox-Fire with King Arthur. I chose to liken the fox-fire to The Holy Grail to give the readers a sense of understanding that the fox-fire can keep the one with it alive forever. In King Arthur's legend, he spends his last years searching tirelessly for The Holy Grail. I really hope the readers enjoy.
