Kroton Foundations

The Kroton Foundations burrow deep into the Gond planet as the root structure of the alien ship. The Doctor observes throbbing organic tissues here, confirming the machine's living core beneath its crystalline exterior. Invasive roots sustain the Krotons' predatory lifecycle, draining mental energy from companions like Zoe and enabling their dominion over the Gonds. This unvisited subsurface realm heightens the threat, turning the ground itself into an extension of the ship's hunger.
