Dynacon Thrusters (Starboard Four Thruster Array)

A quartet of glowing blue propulsion units mounted along the spine of the Zygon-siphoned spacecraft. The thrusters fire without visible exhaust, pushing the massive vessel upward in eerie silence. Their activation requires precise verbal commands, betraying advanced alien engineering. Broton's deliberate pronunciation of the command echoes the thrusters' mechanical precision. The Doctor notes their function with grim recognition, the first unambiguous sign of hostile intent. This array consists of four thrusters, including the specific Starboard Four Thruster Array unit.
