This is Krislan. He prefers "He", though "They" would be more accurate. He's tired. Tired of the lessons he runs for the younguns at his dojo, but that's good sort of tired. Tired of being seen as some sort of hero for his history, but that's an okay sort of tired. Tired of not being able to catch up with friends from his adventuring days. Tired of watching the people he cares about come to harm, being the one to survive when they fall, and having to carry their dreams with him, that's the hard sort of tired. Tired of knowing that when he finally gets some sleep, he's going to relive his mistakes, and see, again and again, what that did to his friends, that's the worst sort of tired.
Despite it all, she's with him, or, within him, and he will see that everyone who put their trust in him will have their dreams carried out, and their legacy remembered.
That, is why he is training the next generation.
