"Do you remember the fourth trial of my inheritance?" Theodor asked.
"The one with all the math and the fire?" Kyle asked.
"Yes," Theodor confirmed. "This is how you obtain Fragments. The only difference is that getting an actual Fragment is much more difficult than understanding this bit of artificial fire I placed."
"Okay," Kyle said, "you told me how to get them, but I still don't know what they are."
"I was getting to that," Theodor said with a snort.
Kyle waited quietly.
"There are rules that dictate how the world works. Why is fire hot? Why does wind move? Why are you being pulled downwards? Why does time move forward?" Theodor said.
"Physical laws," Kyle said. "Stuff about Newton or something like that."
"Newton?" Theodor asked with annoyance.
"Forget it. Not important," Kyle answered.
Theodor snorted. "In theory, everything in existence can be broken down into Ether."
