Fungoids repelled by artificial light

The group stumbles upon a field of light-sensitive fungoids in the alien jungle, which immediately begin encircling them. The Doctor recognizes the threat and orders a retreat, but the creatures' aggressive movement forces a chaotic scramble for safety. When an unknown artificial light source suddenly activates, the fungoids recoil violently, revealing a deliberate pattern of illumination forming a corridor through the jungle. Ian quickly deduces this is no natural phenomenon but a constructed path, likely created by intelligent beings. The Doctor, though wary of the implications, agrees to follow the corridor, seeing it as their best chance to evade the Daleks and the robot doppelganger. The discovery raises critical questions: Who built this path? Are they allies or another threat? The moment shifts the group’s survival strategy from evasion to exploration, deepening their entanglement in Mechanus’ mysteries while underscoring the planet’s hidden technological sophistication.

Analytical and cautious, with a hint of excitement at the discovery of intelligent design on the planet.

The Doctor investigates the fungoids with his walking stick, deducing their light sensitivity and ordering a retreat when they encircle the group. He observes the artificial light pattern forming a corridor and, after initial wariness, decides to follow it, recognizing its potential as both an escape route and a clue to intelligent life on Mechanus.

Goals in this moment
  • Protect the group from the fungoids and Daleks by exploiting the illuminated corridor.
  • Determine the origin of the artificial light to assess whether it signals allies or new threats.
Active beliefs
  • The fungoids are a biological hazard that can be mitigated through environmental manipulation (light).
  • The corridor’s construction implies the presence of intelligent beings, who could be either helpful or hostile.
