Hearing the true state of the Sith drove a dagger of loss into his chest. Everything he had fought for, and his worst fears had come to pass. The Sith had scattered, and their feigned defeat had become a true one. His worst fears, that Nyrys's plan would lead to the Sith Empire's downfall, had come to pass. What that meant for him remained to be seen- He knew the Sith needed real leadership, strong leadership, but it wouldn't do them any good to splinter here and now. He needed a plan.
"What of Darth Calypso? She proclaimed herself Dark Lord, and she had the power to back that claim. She will be a threat to my leadership if she decides to oppose me."
He was quiet for another moment, before broaching the rest of his thoughts.
"We'll need to find the remaining Sith ourselves for two reasons. The first is to declare my new position, but also to rally them and give purpose and direction. If you aid me in this, then when we crush the Sovereign Knights and their puppet empire, I will give you your wish. The Mandalorians will be whole once more- You will hold Mandalore, and your people will be vassals under the Sith Empire, free to recruit from your own and enforce your own laws so long as you continue to the reigning Dark Lord."
He knew the implications of his words- If he were to be usurped, or defeated, or replaced by another Sith, Tros's loyalties would likely remain to the throne. But that was the Sith way- To take power from those above, and if he were to tie Manda'lor's allegiance to his occupation of the throne, it would put the entire future empire at risk of collapse without the support of the military arm. No- When he was slain, and another had taken his place, they would have the support of the Mandalorians so long as they both respected this deal.
