As you know of, Gears are giant robots that were dug up from ruins that are hundreds of years old. As we can see in the game, the Yggdrisel, Avah, etc have tons of robots at their disposal for their armies. My question is, are all Gears dug up in ruins or is it possible for Ethos to build its own gears and only the really powerful/unique ones dug up, like Welltal.
