· Vengeance on Varos Part 1

Doctor and Peri plot Varos escape plan

With the TARDIS dying in orbit, the Doctor deciphers dying power systems with Peri’s help and hatches a perilous plan. They must reach Varos—a prison planet orbiting in the past—to harvest rare zeiton-7, the only mineral able to restore their ship. The journey is impossible without burning out their last backup booster, a gamble that risks total system collapse but offers their only hope of escape.

Who Was There

Characters present in this moment

2
The Sixth Doctor
Doctor
 primary

Determined but internally fraught, masking anxiety with rapid-fire rationalization and dark humor

The Doctor analyzes erratic power readings with growing urgency, pressing buttons with one hand while reflexively stroking his cat badge for luck. His voice alternates between detached technical explanation and sudden clarity about their perilous emergency plan.

Goals in this moment
  • • Stabilize the TARDIS power system long enough to escape
  • • Reach Varos to harvest rare zeiton-7 before time runs out
Active beliefs
  • • Sacrificing the emergency booster is their only viable option
  • • Zeiton-7 on Varos is their audacious but necessary salvation
Character traits
Technically precise Impulsively hopeful Performatively calm under pressure
Follow The Sixth …'s journey
Peripugilliam Brown
Botanist
 primary

Hopeful yet cautious, oscillating between technical focus and pragmatic acceptance of their high-risk plan

Peri tracks shifting diagnostic readouts, questioning technical phrases aloud, then validates the Doctor’s breakthrough with alert excitement when the emergency booster successfully initiates.

Goals in this moment
  • • Assist the Doctor in diagnosing the power failure accurately
  • • React decisively when the emergency plan activates
Active beliefs
  • • The Doctor’s improvisational solutions are worth risking everything for
  • • Abandoning their current location is preferable to system collapse
Character traits
Detail-oriented Quick to engage Responsive to crisis improvisation
Follow Peripugilliam Brown's journey
