The implications seem to be that the Tenno were some kind of special warrior caste serving the Orokin in an expeditionary frontline capacity in the war against the Sentients, and for unknown reasons turned against their masters once that was over; whereas the Stalker was apparently part of a separate but possibly related, and presumably somewhat similar, "metropolitan" guard corps. It can be speculated that the latter force remained loyal to their shared overlords and was duly all but wiped out in the Tenno coup; the Stalker is presumably one of the few survivors if not the only one still around.

Would certainly explain his (its?) mad-on vigilantism...
