Arena - Tarn The gladiator tradition has been long banned in Tarn, and while this once impressive arena is occasionally used for events, it has long fallen into disuse. It's uncomfortable being in an area so big that seems so empty. At the center of the arena, a large statue of Optimus Prime was erected where a statue of Megatron once stood, as a reminder to Tarn that their loyalties are no longer predominantly purple. Locals suggest that the arena is haunted by the ghosts of the first Decepticons killed in Megatron's revolution. Of course, those are just foolish stories. Or are they? Could he?
