The Flagrant Vandals already deduced that the Temple of Haatumak and her accompanying swarm of independent pirate vessels intended to arrive in this star system.
The invisible Acolytes stationed aboard almost every vessel of the Flagrant Swordmaidens hadn't been placed there for sightseeing. The only conclusion the Vandals and the Swordmaidens could make was that they'd been placed as a fifth column placed ahead among their ranks.
As long as they utilized their strange form of stealth to remain completely unnoticed, they would be in a prime position to facilitate a two-pronged attack once the main force of the Church of Haatumak arrived and commenced their attack!
With the key to enter the Aeon Corona System in the hands of the Flagrant Swordmaidens, the cultists who plotted against them from the start needed to make their move very soon if they wanted to obtain the key.
