Kroll's Power Symbol

A jagged, metallic relic pulsing with an eerie inner light, the Power Symbol resembles a ritual object scavenged from Kroll’s aquatic depths. It hangs above the temple’s altar on a broken chain, its surface etched with alien glyphs that writhe when active. When the seventh ritual begins, the Symbol emanates waves of green-tinged precognitive energy, temporarily binding the Doctor and Romana within its influence. The Swampies—especially Ranquin—regard it with reverent terror, claiming it channels Kroll’s voice directly to its wielder.

S16E19 · The Power of Kroll Part 3

Ranquin summons Kroll while Doctor resists

The Power Symbol hangs above the altar, pulsing with an eerie inner light as Ranquin invokes Kroll. When held by Kroll, it allegedly grants precognitive power, but the Doctor skewers its origins—exposing it as a stolen relic used to manipulate the People of the Lakes. Its presence fuels Ranquin's zealotry.

Before: Hanging above the altar, its green-tinged light faintly glowing in preparation for the ritual.

After: Unchanged, though its hollow nature has been openly challenged by the Doctor.

Rohm-Dutt reveals Thawn’s conspiracy

The Symbol of Power hangs above the altar during the ceremony, its eerie inner light pulsing in time with Ranquin’s invocations. The Doctor confronts Ranquin about the Symbol’s history and purpose, linking spiritual rhetoric to Thawn’s political machinations. Though not visibly activated during the confession, its presence looms as an omen of divine (or engineered) control over the ritual's outcome.

Before: Pendant above the altar on a broken chain, its alien glyphs faintly glowing with an eerie green light.

After: Still suspended, its light dimmed in the torchlit chamber, its role overshadowed by Rohm-Dutt’s human confession but symbolically significant as an artifact of divination and deceit.
