Ha ha, I really like your take on "chronomancy" rather than a very broad look its really narrow and in the here and now (ironic). I find the ball player thing hilarious since my buddy is doing something similar. A minor league ball player, an "aeromance" he uses wind to propel his landing hits clear out of the park. he decided to keep the player a minor league player by giving him a horrible batting average (and making him older and thus less likely to be upped to the majors)

Great character btw.. id say great minds think a like but i dont want to insult you (knowing my friend  )
