Reiko had donned her own robe once more while she listened to Kayden. Now, with his head in her lap, she stroked his hair gently, staring down into his eyes. She had not heard of 'chi' before, but it did remind her of other things that she had heard of.
"In our village, we heard about mana, which sounds like chi," Reiko said thoughtfully. "The stories tell about heroes who had more mana in their bodies than most humans. They trained their bodies long and hard in the mountains to build their already extensive stores of mana, and that enabled them to perform extraordinary deeds. In the end, many gave in to pride, and used up their mana doing selfish things, and caused their bodies to fall apart. Did things like that actually happen?" She wasn't worried about using up her own chi or mana, as the stories told by her mother when she was a child had warned her about using powers selfishly.
