Necroworld
The Necroworld is the cemetery hollow-planet tended to by the legendary mute neutral, also known as Necrobot. He transformed the blasted world into a beautiful garden, filled with holographic statues of every living Cybertronian, which he would switch off when the Cybertronian died. Around the bases of the statues, he planted flowers crafted from the residual spark energy of whoever the statue's real-life counterpart was responsible for killing. It is also where "the fortress", the Necrobot's base of operation, can be found.
From space, the planet appears to have two unnamed moons. One, much larger than the other, has it's own rings.
