>>15487992OOParts are an actual thing. Basically an artifact that exists from a time that it shouldn't be possible to find.
Like a lazy example would be to find a fossilized car.
In the case of the Sundial, it was stated that they didnt' have the technology to make the Sundial back then and that they might have used a pokemon's power to create it.
case in point: Diancie's crystals are the same color as the kind that the sundial are made of.
