chapter four: One week later

It had been one week since the last visit from Professor Dumbledore. Batman knew from Alfred that Dumbledore was probably the most powerful wizard in the world. He also knew that his identity was safe with Dumbledore. However, he still had to be careful.

And so, here he was in the Batcave, giving his list of conditions to the Professor.

"First condition: I will not be staying in at Hogwarts." it was short and to the point.

"Agreed." Dumbledore knew that the Dark Knight would never give up protecting his city, even though he had many allies.

"Number two: I travel my own way."

"But-" Dumbledore started to say, wanting to let the Dark Knight know that Hogwarts was protected by many magical spells, and that no human can find it without the help of another wizard.

"I will find a way, professor"

"Number three: Here are the plans for a classroom, build them according to your ways, but follow this plan to every detail"
Bruce said, handing a set of blueprints over to Dumbledore.

Dumbledore, nodded, accepting the papers, then made them vanish inot thin air. "The classroom is now being finished as we speak"

"Number four: I want complete layout of Hogwarts"

"Ah, you'll have to talk to Harry Potter about that. He is the owner of the only map of Hogwarts that ever exists. you see, even I lose and find rooms everyday."

"Number five: Here is the schedule I have planned. One hour a day is all that I can stretch. It is not negotiable."

"Understood."

"Number five: My Identity will remain a secret and I will dress as I please." Batman added this condition, thinking that there was some sort of dress code for the teachers.

"As you please."

"Number six: I would like access to a history book of the wizarding world, a profile of different wizards and their powers, and a list of spells and potions and their antidotes."

"You will have full access to the library." Dumbledore knew that the Batman only wanted this information in order to help protect the muggle world from any rampant wizard, and he knew that the possibilty of Voldemort taking out his rage on muggles was very very strong.

"Thatwill be all. Trust that I will be there when the first class needs to be taught."

"Might I make one small request?" Dumbledore said to the silent form of the Bat.

"We have a tradition of introducing teachers to students and perhaps you could attend the opening dinner of Hogwarts"
Dumbledore it would be highly unlikely that the bat would agree, but the effort was worth it.

The Bat turned his back. Dumbledore took this as a sign of dismissal, and apparated out of the Batcave.

Batman then turned to his newest creation: A batsuit made of integrated Nomex-Kevlar, with the same featuresashis old suits, exceptfor one more type of fiber: one synthesized from Nth metal.

"Let's show them what muggles are capable of."

These words echoed through the darkness of the Batcave
