Geometry Cube

Geometry Cubes, as referred to by Raven, were nanite-based portable substratic supercomputers developed by the Precursors. They looked like a handheld cuboid containing many smaller abstract geometrical objects that rotated on their own, coloured in clustered segments. These were built from the Precursors' version of reality-altering nanotechnology. On "failure", all segments of the cube would turn a single colour.
