Warpstone

Warpstone is a seemingly impossible isotope of Uranium that exhibits anomalous characteristics. Officially it is known as Uranium-259. Disturbances in gravity, electromagnetism and the release of an undetectable form of radiation have all been observed. The latter is theorised to be a fifth force of the universe, not originally from our own, but believed to be leaking from the Dreamspace. Warpstone is a fissile material, but extremely dangerous when used like this due to its unpredictable effects. While the process of refining U-238 to U-259 is unknown, clusters of this isotope can be found all over Oceania, mainly in Australia and Tasmania. It is theorised that all warpstone in Earth came from the same meteor that struck the planet 800,000 years ago during the Enigmatic Impact Event.
