I like your thinking, but I doubt this very much. But there is the smallest of possibilities that it may have something to do with that, maybe something else. As already stated, Relic Castle was eventually buried in sand, Abyssal Ruins sunk ( most likely) to the bottom of the sea, and Dragon Spiral is still standing. It's possible that there was a war between the three, this may mean that Abyssal, having no "special made" pokemon of it's own, was defeated. Then, Relic Castle had Sigilyph while Dragon Spiral had Golurk. Ghost defeats Psychic, Leading most likely to the defeat of Relic Castle. This means Dragon Spiral won that war. Considering that Reshiram or Zekrom is found by N at the top, they made of had help from the legendary beasts. This goes against legend of them stopping the war, but as we know, legends may change after a while. But still, Groudon is the ground maker, which can be turned to sand, hence Relic Castle. Kyogre is like the king of the ocean, hence Abyssal ruins, ( this also may be given a hint to who " king" is). And finally Rayquaza, king of the skies, hence Dragon Spiral Tower, which stands tall in the sky.

Sure maybe she likes investigating them, but she knew exactly how to operate the Arceus event in HG/SS. Also, as Dragonshock stated, a swimmer states that she dives down when no one is looking. It wouldn't surprise me if she already knows or isn't telling us something.

Scaring all the pokemon away, it might not be that of a Unova pokemon. Perhaps it is a Kyogre, maybe it's arceus ( i highly doubt it), it's also true that the landorous, thunderous and stormadous aswell as cobalion, virizion and terrakion and keldeo. They all have not had much of a backstory, including genesect and melottia aswell. I doubt the theory, but it may be genesect. Despite being a steel type, it has the disc's which may be used for electric attacks, ( super effective against water types) and it also happens to be a bug type ( also super effective against water types). + It looks scary =P.
