Humans
"I have some spells capable of hiding our mana and diffusing it to make it seem like we are in smaller realms. Furthermore, I plan to make a large area dragonfly-free, but that is only in a few hundred crystal cycles." The cat was happy to hear the beginning and then depressed to know how long it would take.
"I have at most two more life cycles." The cat said darkly. He felt he could live another two centuries and reach 350 cycles, a little higher than the human average.
"Don't worry about it, I need you to understand some mystical techniques that will make you able to live longer. But first, you have to learn to read and speak human language." Kayden took a small book he wrote this week and threw it to the cat. Furthermore, he gathered a bunch of information and transmitted it directly to the animal.
