I had a theory on the DH spy. Bear in mind that I'm too lazy to rewrite it, and its copied verbatim from my locked topic
My theory is that Gatherer is the OoMN Spy. Why? The OoMN leaves behind no trace of themselves when they operate (or at least try to). For a Dark Hunter, a member of a seedy bounty hunter organization, to pick up their trail must be near impossible. If Gatherer is the OoMN spy, then, of course he would already know about them, and could 'pretend' to be tracking them; that would be the perfect excuse to report to them about the goings-on on Odina.
Now, many will be quick to point out on the BS01 page proof that he is not the spy. However, I was not able to find any proof backing up that fact, so I believe it to be false. If someone could bring forth proof on that, it would be much appreciated.
