Zarkest is the most volatile of the Celestial Elements. Comparable to hydrogen in conceptual structure, it contains enough energetic density that a single molecule can propel a starship to lightspeed.
Properties
Holds extreme spacetime-bending energy
Perfectly stable until intentionally activated
Reacts by warping geometry rather than burning
Incredibly dangerous if mishandled
Emits faint exotic spectral signatures
Even microscopic leakage of Zarkest can devastate moons or planetary surfaces.
Distribution
Zarkest is hidden within the silicate-rock cores of gas giants in Lethurîa, held stable by intense pressure and gravity. The First-Flames concealed it there out of fear of misuse.
