Doctor uncovers Grid Room function

The Doctor enters the Grid Room to rescue Turlough from the vacuum trap and learns it serves as both a sensor array for the ship's ion drive and Wrack's weapon amplifier. Guided by Turlough's claim that Wrack hid secrets here, he identifies the red eye above the grating as a massive amplifier and deduces Wrack's method of focusing its power through small artifacts granted to rival captains. This revelation transforms the Grid Room from a simple control space into a key piece of ancient technology central to the deadly race.
