UEE and the Kr'Thak. Secret allies?

Could this be the face of our
oldest enemy?

The Kr'Thak. No one has ever seen one, so we've been told. But what do we really know about them? We do know they've been a long-time enemy of the Xi'an. But haven't the Xi'an helped us overthrow our overlords in the past? Maybe the Xi'an aren't the enemies here. Throughout our history, truthtellers like me have written about another race of aliens. Ones unlike the friends and enemies we've made across the stars today, a reptilian race unlike the Xi'an, could it be that the Kr'thak are that race? Have they been working together since before the dawn of human spaceflight with the organisations that influence so much of society today? The evidence seems to fit, the Xi'an might be our only ally in this war, but it is far more likely they are competing with the Kr'thak for a place at the table.

We do know that the Kr'thak are a nomadic race, is it possible they visited Earth in their travels before? Influencing early human development maybe even establishing secret societies that still conduct their operations today. If this were the case, it would only make sense that the societies would contact their founding partners and work with them. The combined force of the UEE and the Xi'an Empire could easily crush any power in the galaxy, why haven't we went ships to help the Xi'an? Maybe our "masters" don't want any harm to come to their friends.

An even more terrifying thought, the Xi'an don't give anything away. They're as wary with favours as the most stringent Banu trader is with his wares. One can only assume that when they sent in elite commando squads to sabotage Messer, they had their own reasons for doing so. Maybe this wasn't a preemptive strike against humanity, maybe this was just a continuation of the Spirit wars. We have very little information on Messer's early life, could it be that he was a Kr'thak agent? Planet to turn humanity against the Xi'an and finally end the Spirit wars with a brutal Kr'thak/Human victory? If so, what would become of us after we had served our purpose? Are the Kr'thak above slavery of an entire species? We just don't know.
