ShadowZero
A wreckage is spotted drifting into the orbit of one of the planets of the Jinaris Empire, in specific, the capital. Seemingly precursor in origin, it is hastly collected, though only to reveal something out of the ordinary.
The wreck was just a husk, and within it, resided a single object: A small 10x10x10 smooth cube made of metals, the artifact is scanned, revealing atomically-constructed internals activated by a switch etched on the outside. The object is soon taken to someone important should they make the decision of activating it.
