Secondly, Charlotte indeed saved the entire Harcos Clan.
Third, the Bloodline, after all, is a race that values hierarchy, and given a True Ancestor who had regained "reason," it was unreasonable for the now-mythless Harcos to refuse submission.
Of course, submission is one thing, but turning the Harcos Bloodline into her own followers would require more time.
But that was a concern for later, as the Great Prophet Margo, who was in charge of the Queen's Palace, had already pledged loyalty to Charlotte. Since the Queen's Palace had always been a "Divine Right" institution of the Harcos Clan, a shift in faith was just a matter of time.
Naturally, like the Nais Clan, apart from the Great Prophet Margo, the Harcos Bloodline was also unaware of Charlotte's true identity.
She still received the submission of the entire Bloodline in the guise of an adult.
As for the "return of the True Ancestor," that too was sealed as a secret oath within the blood vows of Harcos.
