No, no.
I mean I am using a Dictum to Enthrall the leader of the expeditionary force. I'm spending 5 PL on doing it. Can I take control of the expeditionary force this way? If not, I continue to defend my people. I also send the following reply to their ultimatum, but only if I can't take control of their force!
============
"Anabstercorian! Come out with your hands up! You are wanted for an act of war against the people of the Eternal Empire!"
Anabstercorian swoops down among them, landing in one of those crazy, threatening looking anime stances. << Whatever. >>
Ba-WHAM! Mindblast! The few whose brains don't shoot out their eyes, ears, and nose are left gibbering lunatics for the rest of their lives - Which is about six seconds, when Anabstercorian nails them again. He swoops up and heads back underground, tearing through Eternal Empire forces.
