"You say you believe greek mythology, then search there. Seek out Phantasos, if it's the hell hound that's warning you, then consider things like, he stops the living and the dead from colliding (usually, I mean unless your Orpheus, Hercules, Psyche etc etc) he's a guard. If Pax means peaceful, maybe it's a warning about conflict, maybe it isn't your conflict, but a friends or something? Could even be a warning against oposites, because he seperates the living from the dead, which are oposites. What's the hell hound linked to, that's what you should think. Hope this helped x"
