tsoonid

tsoonid is a fictional mineral described in speculative fiction, tabletop role-playing games, and some science-fiction media. It is not a real mineral documented by measurable geology, and there is no single canonical description across sources.

Origin and naming

The term tsoonid appears in various in-world languages and is sometimes explained as arising from roots meaning glow or shield. Because it appears across diverse works, etymology and meaning can vary by author, setting, or game system.

Physical characteristics

In most depictions, tsoonid is a dense, metallic-looking crystal with a blue to violet iridescence. It is described as having a high refractive index and a metallic luster; common crystal habits are elongated prisms or tabular forms. Reported hardness ranges from approximately 6.5 to 7.5 on the Mohs scale, with strength and fracture behavior that are often highlighted in fictional material science.

Occurrence and formation

tsoonid is said to form under extreme conditions, such as high-pressure, high-temperature metamorphism or extraterrestrial impact environments. It is frequently described as occurring in veins or disseminated grains within basaltic or ultramafic host rocks and often alongside other rare minerals in fictional geological settings.

Uses and cultural role

In-universe, tsoonid is valued for its strength-to-weight properties and distinctive optical features. It is proposed for advanced alloys, energy storage concepts, photonic or spintronic applications, and sometimes as a decorative material in jewelry within its fictional ecosystems.

Notes

Because tsoonid appears in multiple unrelated works, there is no single canonical definition. Details vary by author, setting, and game system.
