Lark shrugged, desummoning his sword, "I can't teach you how to use magic, kid. I can only tell you where it comes from. Heck, who even knows if you've got an aura at all? People who can use magic are rare as hell!" Lark paused, and shrugged again. "You won't be able to harness any magical abilities if you just try really hard. Sometimes they're gained from more than inherent talent, like from a deity's spirit, or a magical artifact... Ki may not be trainable, but if your Ki is strong enough, sometimes it will leak through regardless of whether or not you're conscious of it."
