The Mysterious Falconer

Harry, Ron and Hermoine had all entered into Hogwarts along with all of the other students. All of the new comers had been sorted and everyone was ready to feast once Dumbledore had given the announcements of course.
"Welcome to Hogwarts, new and old. I would like to remind you that the forbidden forest is off limits to everyone and anyone here at Hogwarts. Another Defense against the Dark Arts teacher has joined our staff this year and he shall be arriving shortly and..." Just then the doors to the great hall flew open and a giant falcon screamed through the doors. Everyone turned their heads to see what had opened the doors to end up seeing nothing. The disappointed turned to enter shock and see a person, cloaked standing on top of a giant falcon. The person jumped high into the air almost touching the top of the great hall. The person, or at this point most people thought creature, then flew down, like a rocket, head first to where Dumbledore was standing.
They saw a leather gloved hand reach out and motion for Dumbledore to lean closer. Dumbledore did such and the very few at the front of the great hall heard the quietist of whispering. Then the cloaked person pulled out a long, pewter sword that was magnificently decorated at the handle, and placed it, with the tip at Dumbledore's neck. When seeing this many of the students and the teachers pulled out wands at the ready. The man put his sword away and raised his right hand into the air still having his dark midnight blue cloak covering everything else.
"Disarmoraid," the man shouted in a dark, deep, full voice. A blue misty blast shot out in a dome shape. Everyone with wands at the ready was disarmed; in fact their wands had seemed to disappear.
"It seems," Dumbledore started, "it seems that your new professor would like to say a few words, without being interrupted."
"Very true Albus. I am your new professor." It was that voice again to Harry it sounded evil or even dangerous. To Ron it sounded like a second Snape with more evil. To Hermoine it sounded dreamy. Harry turned to look at Ron to get a worried expression, which was what Harry was honestly feeling in the pit of his heart. They both turned to look at Hermoine who was in a lala land state staring at the new professor.
"I am your new professor. My name is Vincent. Just Vincent and nothing more." Draco found this amusing so he had to yell out.
"You must be crazy every one has a last name and besides its not like we can call you Professor Vincent." Every one around Draco was either chuckling at this or worried.
"Actually Mister Malfoy you will call me Professor Vincent and since you're so eager to talk please tell me on of the most dangerous dragons." Harry was still trying to figure out what was wrong with Hermoine. He poked her a couple of times.
"And you Mister Potter, please tell me the second most dangerous dragon."
"Hungarian Horntail," Draco said so confident.
"Ukrainian Ironbelly," Harry said more directed at Draco.
"Very good, both of you. Watch." Professor Vincent then waved his hand around in the air and said summonio. Everyone waited, then out of thin air appeared two dragons. One of the dragons was dark black with bronze horns and yellow lizard like eyes. Everyone could tell that was the Hungarian Horntail. That meant the much larger, metallic gray dragon with deep blood red eyes was the Ironbelly.
Everyone saw these and fear appeared in their eyes, even in the teacher's eyes. Professor Vincent then jumped up very high once again and moved so fast that no one could exactly make out what he was doing. Some people saw with mauling the dragon, the Horntail, with hi bare fists. He then landed on the falling dragon head, jumped flipped three times, pulled out his sword and sliced the Ironbelly into countless number of pieces. He pulled the sword upwards and thrust it forward. There then lay two dead dragons bloody on the great hall floor.
"That my friend is true defense against the dark arts," Professor Vincent proclaimed. "One more thing that falcon is my pet leave it alone or it will maul you with its talons. Now let us feast." Everyone sat there in shock.
"I said feast." Just then everyone was scared out of their wits and began eating.
