Lark laughed heartily and nodded his head. "Yea, she's a beaut. Now, watch closely," Lark said, lowering his sword to the ground. In a slow motion, he rose it up and arced it around his entire body, leaving a trail of water behind it that floated in air for a moment, and then rained down. "Arcane energy is the base of all matter and, well, energy! Fire, water, earth, air, you can potentially do anything with it if your body's capable. Most magical people have a certain affinity though, based on their arcane energy. I don't, because I'm pretty amazing," Lark boasted. After that, his blade began to glow a bright yellow, making the air around him and Jenso ever so slightly warmer.

	"This is Ki! This stuff can vary in strength, and you cannot train it at all. It makes people a shit ton stronger if they harness it though, and in some very rare situations, you can expell your aura in energy type techniques that are devastatingly powerful!" Lark swung his sword to the right and unleashed a wave of white energy that sliced into the trees and cleared a path forward. "Like that. Sometimes Ki is so powerful, that it shines though even if you don't harness it, and grants people amazing abilities, like increased regeneration, pain reduction, strength enhancement, and insane agility! Stuff's pretty nifty, but unless you're like me, it's pretty rare to find somebody with a strong residual Ki flow."
