Hi, I'm the same person who made the fan theory that Chronos was the stone giant, and now I have another one.
As you know, Leon helped Emily learn to harness her powers in books 2-4. how would he know so much about stone magic? I know he says that "The Elders" taught him about it, ...but the way that he teaches Emily about "everything having a life force" seems almost like he's experienced having stone magic himself.
I think that Leon is a stonekeeper, and he just keeps his stone hidden. I feel like I wouldn't let myself keep the responsibility of teaching a Stonekeeper who is supposed to SAVE THE WORLD to harness her powers if i didn't know how to do it myself.
FACT: Leon knows a strange amount about stone magic.
FACT: In book 8, when Ikol's little assistant is showing Emily around the void, she met a crowd of stonekeepers, and one of them was a fox. I believe that was Leon.
As I stated before, i'm the same person who made "Chronos is Stone Giant". If you think fan theories should not be articles, please tell me how to start a thread.
