So are all Harding's chalkings Rithmatists?
Calloway (the third kidnapped student) said "there seem to be hundreds of them" (and I think hundreds of people appearing when Harding is defeated would have been mentioned).
If so, what happened to the rest of the chalkings when the captured Rithmatists reappear?
PS: aren't we all glad the wild chalkings reformed when killed or doused in acid, knowing now what they really were ?
