This is likely the case... Maybe the Demon Crown owner at the time destroyed the entire world. Only a few people survived and these people happen to be the Sakamoto family with Booster and Date.. Maybe more people, who knows.
I find it hard to believe that even a floating island even with the power of the Demon Crown and frenzied creatures at their control could destroy the world...
But, how the War is mentioned from 10 years ago makes me believe it really was a significant event. Not just a battle... But how could the island take on the world?
Well here's one thing to consider. It has only been 10 years since the War. And yet somehow the knowledge of the Red Flower's power over the Mimigas has vanished from even the Mimigas themselves... How can this be?
Do Mimigas have really short life spans? ... I don't think so...
I think that the just about the entire adult Mimiga population was wiped out in the War. That means the Mimigas that survived were simply children, growing up without parents...
We saw how powerful Toroko became, and I don't think she was very old at all, even Sue as a transformed Mimiga human was pretty kung fu powerful lol
So maybe... the adult Mimigas who could have been warriors, hunters, or full of knowledge about the island maybe... Perhaps they turned into creatures much more dangerous than the ones Quote had to deal with in Cave Story.
Still, even if the adults were much more powerful, causing a War?
And if the countries of the world can create robots and helicopters and hover bikes! Wouldn't they probably have big weapons, like missiles or lasers of some kind? So they could attack the island directly when it became a threat...?
That means maybe there is some way the island is protected..
Just checked Curly's dialogue, she says the robots were sent from countries on the earth's surface... Not all countries just countries. So some countries must have opposed the strike against the island. Although once Miakid got ahold of the Demon Crown, she says he began his assualt on the Earth... He probably forgot his alliegences to the countries that he worked for at that time... Maybe...
In any case, he had frenzied Mimigas and maybe some creatures from the island to help him do battle... [maybe the sky dragons too?]
Also, I wonder if the Red Flower works on Earth's creatures? If that is the case... then to get more soldiers all he had to do is grow more red flowers...
From what the Doctor said though it wasn't strong enough to affect humans, but it should work on animal-like creatures...
If he did anything like that, it'd basically be like turning the world's creatures against the world. Now THAT would be a War...
The Mimigas are probably the best of the soldiers though since they are intelligent and seem to be related to the origins of the island maybe...
*cough* and back to Arthur : He could have been one of the eldest of the children/teenagers left, and perhaps he DID know about the Red Flower, and maybe even a safe way to use it? I'd say there's a good chance Arthur met Quote and Curly back then too... If any of the Mimigas knew the whole picture of what happened it would have been Arthur. Of course he dies to the Doctor or Misery probably... We saw how King could make Balrog ouch!
No defense against magic though...
One thing that bugs me is how far the this research team (Itoh, Momorin, etc) made into the island. It's known that they landed at the Balcony. From there you can take the route Balcony->Last Cave->Plantation->Outer Wall->Mimiga Village etc.
I wonder though, did they Originally land at the balcony? We know the helicopter is there, but that means the Crown would have been right there in front of them immediately. And it IS a big island... There is no evidence to say they landed elsewhere, but moving the helicopter later isn't really that hard to believe.
Sue's letter says the Doctor was there to meet their medical needs... and did so until he found the Demon Crown... So, most likely it was at least some amount of time before he found the crown... Otherwise that line about 'and did so at least until he found...' shouldn't be there.
Also I have to at least bring up the fact that in the opening cutscene when the Date finds the Crown... it's all dark! Unnaturally dark. You Could reason that maybe those ruins were buried, or something and that could explain why the Crown was hidden. [or there's a second crown room, or the balcony is in a hidden cliff... I mean when the island is collapsing, Rocks!!! Are falling from the sky!! [The sky is falling!] lol so that could mean that area could be well hidden...
Also you'd think that the scientists from 10 years ago probably had places setup as well, unless they were all destroyed... It'd be more likely they'd land at a place with a computer already setup with a landing pad
No evidence of course... but it says humans used to live on the island, scientists. I'd imagine a lot of stuff used to be on the surface of the island... maybe. Although after the War happened survivors would have had to hide underground to be safe...
Jenka seems at home underground... but recall that Last Balcony is on the surface, with ruins of what used to be some place. And where there's one ruin there is probably more scattered across the island! Maybe...
Momorin and Itoh are seen in Plantation, with some kind of backup plan in case things went wrong. Sue, her brother and Booster might have gone a little farther until they got captured by the Doctor...
And now the last piece, where was Booster all the time? I don't remember he saying where he comes from... And I don't remember why Kazuma was in the shelter either...
Sue's letter states that she arrived with Booster, her mom, brother, and various assistants... [meaning Itoh and maybe a few more...]
As for Booster's whereabouts.. Well, the Doctor might have kept him close, probably on the Balcony area. Remember that house that leads to hell had Booster's notebook, that tells about his Booster technology being used to explore the island... and even talks about v2.0... "If he lives long enough..." From that phrase you could guess that he might have already been under duress. As in under the Doctor's orders...
How did Kazuma arrive in that one place? Well after escaping the prison full of Mimiga, there's that teleporter right there... I'd have to assume that's how he got there.
One of the Mimigas behind bars say this :
"There used to be a couple humans in here too, but I haven't seen them around... Wonder if they got away."
That makes me think Kazuma used that teleporter that is conviently right there which leads to that place lol [unfortantely it seems it's a one way trip for whatever reason...] I'm not sure if Booster used the same teleporter to get there or not though. He seems to have knowledge of teleporters, as he can fix the one in the labyrinth...
About the sprites: the Mimigas are awesome. I liked Toroko and Arthur
Curly is also awesome.
Yeah they are cool
I would use them in my mod if I could ever figure out the story of 10 years ago...!
Oh, and just a thought: Maybe the teleporters were set up by a previous Crown Wearer, and if my "Cthulthu is a hologram-using guide" theory is correct, his duty was to inform travellers where they were. </off-topic>
Interesting theory
Although remember at least that one Cthultu is the real macoy... er he rescues Curly from the water and puts her in bed...
