Rereading the first post, I'm pretty sure that narrative write up isn't the same thing as the hidden rules/red rules. Therefore, if there are 3 people who can mess with how Karifean does his write ups the language is vague enough that we don't know if they're human or witch either. So saying there are three witches seems to be a suspicious conclusion since the evidence is circumstantial at best and open to interpretation. Moreover, Karifean is careful enough when writing that he wouldn't mix the two up (narrative and hidden rules) unless he was purposefully trying to obfuscate.
