(Assuming Trelene does this)
The message comes up on the handcomp. Trelene notices the message is erasing itself, and all the other messages store on the handcomp, as it appears. The message is in text only, bears no origination signature, and has been bounced off two different asteroids making any proof that the mercenary vessel originated the transmission near impossible. "Dvonn. You know we're here, and that at somepoint you're going to have to leave orbit, at which point you will be obliterated. We would prefer to take that ship intact, and are authorized to offer you, the crew, and any surviving passengers a substantial credit sum to secure your willing surrender and subsequent cooperation. This is the only offer of mercy you will receive. Do not attempt to flee the system or you will be destroyed. Do not attempt to dock with the base, or you will be destroyed.
