Gevenite

Gevenite
Mineral found on certain planets critical to matter tesseract generation for the Space Drive.

While gevenite is a very valuable ore and critical to safely using the Space Drive to traverse great stellar distances, raw genevite interacting with stellar material can cause instability in the star's mass, creating an explosion powerful enough to annihilate a small solar system. Additionally, the resultant explosion causes a phenomenon in normal space called "gravitic scarring," destabilizing any travel through the former system afterwards via Space Drive.

A particularly strong deposit of gevenite was extensively mined on the planet Caldera prior to the attack of the Magmadivers. Kienan Ademetria send a ship containing a shipment of raw gevenite loaded prior to the Magmadiver attack into Caldera's local sun, destroying the planet and rendering the system uninhabitable.
