Sphere of imminent doom

From 2speccers2tools wiki

Due to the sophants surviving in some form, the Doom Spheres have breached the atmosphere, and have set out to eliminate what caused it to exist. They now have an eye can can see in almost every wavelength, and have two arms. They are unforgiving beasts, being able to track things down even smaller than atoms, and will even commit cannibalism to achieve their goal of fixing the project.
