Vargas strode toward the heart of Draco, calling out in a bellowing voice, though his mind was very much elsewhere.
He'd waited, deliberately, before really planning. When he did this--if he did this, if Cain managed--he didn't want the dragons to suspect. It wasn't that he was afraid of them. He wasn't. It was, first, that Order would have likely let its guard down by now; and second, that there was no point in aggravating the dragon family when they were already willing (most of them, at least) to fight the forces of Order. And they would have suspected the Forge, had he acted right away--because he'd tried to talk to them about it. In retrospect, addressing Dread himself had probably been the worst possible choice, but Vargas did not know the others well enough to be sure. He'd tried to explain that the chrysalized diamond was infected, infested, with a terminal corruption: that Order had taken the white dragon, and that she would never be her own creature again. That she was controlled, manipulated.
To his credit, at least Dread had listened. And he'd seemed... disturbed, even mentioned almost mournfully that he'd been warned about something like this before, but hadn't understood (unsurprisingly). But in the end he was completely unwilling to actually harm his child, too bonded with her, too filled with pointless emotion. Dread's bottom line had essentially been to say that if Bone were happy, he was happy for her, regardless of all else.
Vargas couldn't have that. He'd keep Order from them--protect them whether they liked it or not--and reuse the diamond for something other, something that would serve Chaos instead.
But... for that, he needed Cain. A direct assault would be unwise--the dragon could fly, and Ursa would be full of Praetors and the like that would scurry out to aid her. Better to strike unexpectedly, to end her before a battle had begun, and spirit her stone away before any of the Hive knew what had happened. He'd considered, too, the tunnel that led Ursa to Leo--but he'd discuss these details with his Overseer.
He had to leave some room for Cain to make its own decision, and he trusted it to do so. It had a good head on its shoulders, though Vargas did note with some trepidation that this would be its first true test.
With luck, Cain would be in earshot.
