It spoke. Its voice was only noise to human ears; a rubbery grinding sound like under-inflated tires on an old gravel road. Its long, mechanical limbs raised and lifted as it moved, possibly in some gesticulation, wondering what the tiny, squishy figures were doing, intruding in its lair. The humans spoke to it; explained that they were peaceful explorer from a planet called Earth, long dead and far away. The humans offered it a hand in friendship, and the creature backed away, insulted that the ugly bio-creatures would whip out such an obscene appendage, right there in the throne room.
