In all seriousness it could be a space station of some sort (just look at the Death Star…it looks just like a moon!).
Or it could possibly not be a moon at all. Perhaps merely an oversized stationary meteroid of some sort?
It’s a magic vanishing moon. When the level designers remember it, it’s there, if they forget about it, it’s gone all of a sudden. 
So, let’s assume what us humans would do when they would get back on earth after leaving it for a few thousand years or whatever.
First you would try to establish some kind of save harbour, then you would try to get back into control.
Couldn’t it be a natural rock formation pulled into the planet’s orbit? How about an optical illusion? 
Maybe it’s reflection of the other moon.
Maybe its just another moon for crying out loud!Another planet!
Moons are not planets are they?..They are moons
And yes, it’s known it can be and possibly is “just” another moon, they are just trying to find other explanations for it…nothing wrong with that.
Now now, there’s no need to go berserk. 
We should take a screenshot of the infamous twin moons. I love all these little mysteries.
Moons are called secondary planets.But when I said another planet I meant that the PD wolrd is in another planet!Not Earth.

Well I don’t think two moons necessarily mean the games are set on another planet.
Well, here’s my thoughts on all this:
I’m quite sure that numerous things state the Ancients were human - the one that most springs to mind is in Saga, where Edge and Azel are in the Underground Ruins of Uru. When they enter that chamber containing the remains of prototype dragons, they have a conversation about how dragons were created by humans, and Edge is surprised to find that the Ancients were humans (and presumably not the “gods” they are commonly held to be). Also, there is a conversation where Gash says that the Ancient Age was a time when humans controlled “godlike powers”.
Anyway, about the moon thing: There are numerous science fiction stories that have had extra moons attach themselves to planets. Look at the 2001: A Space Odyssey series, for example; that features even larger cosmic changes (i.e. Jupiter getting ignited into a sun with its moons becoming a mini solar system). An extra moon is quite explainable by fantasy / sci-fi standards, and as the PD series is probably set on a far future Earth (if it is Earth), anything could have happened in the intervening time.
Overall, I think that the important thing is the feel of the setting, rather than the fine details. It feels distant from the world we know; a wasteland created by a foolish humankind’s mistakes. Whether or not the human race is meant to be us, or some future continuation of us on a far off planet, or just some other parallel humanity, seems to be less important than this.
Oh, and the story in the original Panzer Dragoon’s instruction manual also states a few times that the setting is meant to be Earth. Admittedly this could also be a translation error, though.
By the way, is there anywhere else that the second moon appears in the series apart from Episode 1 of Zwei? I honestly can’t remember…
Last time I remember Geoffrey : Earth didn’t have 2 moons!And don’t come up with theories of a moon geeting in it’s orbit or something cause such thinsg don’t happen just like that - moons aren’t just floating aorund ya know?
Anyways, the fact that there is a human race doesn’t eman shis since there are other planets in which human life could thrive.
He said it was a time when “mortals” controlled god-like powers. That doesn’t make them human though. I think it’s clear that the Ancients were related to humans, but maybe they evolved in a way that would make them different enough to make a distinction between the two. If I remember correctly Sestren itself even called its masters “the Ancients” in PD Saga.
It’s also shown in the ending of PD Orta.
If anyone else sugest that the Ancients might not be humans heads will role!!
“He said it was a time when “mortals” controlled god-like powers. That doesn’t make them human though.”
Sorry, my mistake - but the Azel conversation I mentioned definitely does state that the Ancients were humans, and as Azel was around at the time there’s little reason to assume that she would be wrong. PD1’s introduction also states that “thousands of years have passed since a once thriving human civilisation perished in the dust”, which has to refer to the Ancients really. As this is from some kind of omnipotent narrator, there’s no real reason to beleive that that is wrong either.
Anyone who still thinks the ancients aren’t human is either dumb,ignorant or has bad memory.
We’ve had this debate a record number of times now and each time it has gone unresolved.
Basically, any reference to the ancients being human in the English versions of the Saturn Panzer Dragoon games is supposed to be erroneous. The only reference to humans existing in the Ancient Age is contained within the journal of Skiad Ops Endow who alludes to groups of “people” rebelling against the Towers and their creators. Who or what these creators were is debatable. I find the distinction between the ancients and the rest of humanity in the Zoah bible quite peculiar in that there would be no reason to separate the two if they belonged to the same race. Something had to set the two apart, only we’ve yet to figure out what that is.
I’m open to the possibility of the ancients being something other than human but I can’t see how they couldn’t be human. Did these ancients abduct humans from Earth?
Now why would I do a thing like that?
The twin moons would suggest the planet they are orbiting isn’t Earth. Still, it cannot be ruled out.
