"The propulsion system is firewalled from the rest of the grid so that it accepts inputs from only a limited number of terminals, not all of which receive data back. Ideally the drone would plug in somewhere in engineering so you wouldn't have to work around that. Nothing needs to be done to the moth directly." Alaric considers that for a moment, then amends, "That we know of. Obviously we haven't had a chance to experiment with what happens if a moth tries to forcibly extract itself from a disabled harness and the rest of the ship."
