With a downward thrust of the final steak to a force field which he had made out of a couple special power repelling crystals that were welded to a some large metal rods. He then did a last minute check of each and everyone that he had placed in the ground to make sure that they were all deep enough to with stand the force of whatever the students may or may not be able to produce. After it had seemed to be satisfactory he decided to give it a little test run just to make sure that it actually worked considering that he had never actually tested it. So he stepped into the boundary lines of the giant diamond shaped are that he traced out with a line of fire between each point of the metal rods and proceeded to the middle. Once there he stood straight and decided that it would be best for him to start off small and then work bigger and bigger to make sure that he didn't start too big and practically destroy the whole thing before any of the students even got there. He then took in a deep breath, closed his eyes, and extended his arm in a quick thrusting motion while at the same time firing a small, yet harmless fireball out of the tips of his fingers. At first it looked like the ball was about to pass through but with out a moment of delay it quickly evaporated as soon as it had touched the boundaries edge. With a slight feeling of satisfaction he decided that now it was time to take the force field to the next level. Again he stood still, drew in a deep breath, and then this time heaved both of his arms forward with his palms extended before him. In doing so he emitted a rather larger fireball that was about half the size of his body with absolutely no effort at all. Again when it had reached the boundaries of the force field the ball of fire had instantly evaporated into thin air. He was starting to become rather pleased with his creation and felt a quick rush of energy coursing through his body because his new "toy" had seemed to be working.
Nataniel normally wouldn't act like this in front of anyone or even when he is by himself but, seeing as he had a wonderful opportunity to mess around a bit he decided to have some fun. So he stood once again for the final test making sure that he was calm, took in another deep breath, and then he let his fire spirit side completely take control of both half's of his body. By doing this, it allowed him to create one of the most magnificent displays of martial arts fire bending. With a kick of his feet and a thrust of his hands fire was shooting out in all directions while at the same time being quickly dissolved as soon as they touched the edge of the force field. Nataniel felt so good and young while he spun in the air spewing forth a combination of large fireballs, small fireballs, and some rather amazing streams of fire out of all four limbs of his body. After one last spinning kick of fire Nataniel decided to let loose the grand finally. To do this he placed his feet firmly on the ground in a horse stance, in haled deeply through his mouth and nose, then stuck his hands out with a tremendous amount of force and shot forth a monstrous stream of fire from both hands in the opposite directions. The area that he was in grew so hot that the patch of grass surrounding him had been completely incinerated and was replaced by red burning coals. The force field was working extremely well as the fire stayed with in the boundaries almost as if there was a giant wall made out of cinder block standing in its way.
Once Nataniel was satisfied he closed his hands and stopped the fire from streaming out of his arms. He then stood up with a big grin of satisfaction upon his face because now he knew that this invention not only was capable of being used for testing his students, but also for battle as well. That moment was shortly lived as the grin quickly faded from his face and his mind had snapped back into reality. He dusted off the tidbits of ash from his shoulders and walked out of the area that was now filled with smoldering hot coals and ash. He was heading towards a desk that was placed outside for him right next to the force field so he could observe the students as they auditioned for the class. Once he got there he grabbed some paper and a type writer that was specially made to type in braille letters due to the fact that he was blinded long ago and sat down on a small fold out chair. There he waited with his hands folded on the desk and stared out into the distance with his scarred pale blue eyes.
