A good belief you have there. So OT is trying to consume MT as fast as they could. Before Lukon-Ori war end... Heh
Given how little of MT there is to consume, they're taking their bloody time
Unless this is all some cunning ploy to play down their potential threat level whilst preparing to swoop in from the wings and establish their own empire on the bloodied remains of Lukon and Oritolon. It would explain why Khain keeps skulking around our lands faking severe mental impairment...
