Blue Hymetusite Crystal (Nimon Fuel Core)

A cluster of deep-blue crystals embedded in the Nimon's nuclear furnace, their surfaces shimmering under harsh laboratory lights to cast an unnatural cerulean glow. Five spherical glass globes pulse with radioactive light, carried by tribute bearers including Seth and Romana as part of the Anethan delegation's ritual submission. K9's sensors detect extreme radiation levels, confirming the crystals' lethal nature. When channelled through the positronic transmitter, their energy potential destabilizes the fortress walls, its immense power vivid in the raw transduction of raw exotic particles.

S17E17 · The Horns of Nimon Part 1

Doctor discovers deadly hymetusite deposit

The blue hymetusite crystal glows faintly within its transparent globe, drawing the Doctor’s attention. Its identification as hymetusite by Romana and subsequent radiation readings by K9 confirm it as a deadly radioactive mineral. The crystal’s presence underpins the entire discovery and threat assessment.

Before: Embedded within the transparent globe, concealed among other cargo in the ship’s storage system

After: Visible and identified, with its radioactivity confirmed by sensor data and spectroscopic analysis

S17E19 · The Horns of Nimon Part 3

Doctor and Romana uncover Nimon weapon secrets

The blue hymetusite crystals embedded in the nuclear furnace serve as the raw energy source powering the positronic transmitter device. Their immense radioactive potential is confirmed by K9’s analysis, underscoring the device’s destructive capacity. The Doctor and Romana realize their potential not only as fuel but also as targets for sabotage.

Before: Embedded in the Nimon’s nuclear furnace, glowing dangerously under laboratory lights.

After: Still within the furnace’s core, their energy presently being channeled toward the transmitter and destabilizing the lab environment.

S17E19 · The Horns of Nimon Part 3

Doctor summons K9 to analyze Nimon device

The blue hymetusite crystals, embedded in the Nimon’s nuclear furnace, serve as the transmitter’s primary energy source, their radioactive pulses feeding the positronic circuit. K9’s sensors confirm their lethal radiation, underscoring the peril if control of the system is lost. The Doctor and Romana infer their role in destabilizing the fortress walls when channeled through the transmitter.

Before: Embedded in the nuclear furnace as part of the Nimon’s ritual apparatus, pulsing with deep-blue radioactive light

After: Functionally identified as the high-energy fuel core powering the transmitter’s transmission capability
