From my understanding, "700 million years" was a statement made in reference to point B(the present/the period of time Anos and Garlonoa originates) to point A(the beggining of time), put it simply, everything within the perspective of Anos and the pope. However, its a proven fact that point C(the future) also exist where point B is endlessly heading towards , constantly leaving behind traces as a result. Hypothetically speaking, it wouldn't be an unreasonable conclusion for the overall amount of traces to be directly proportional to the overall reaches of time itself, while the Land(the domain) SHOULD definitely have the capacity to hold this exact scale of traces, and still be infinite in comparison to it.
That said, I'm absolutely clueless on the the ways and mechanics of this site. So ya, just my two cents in this subject.
