The Sun Atlamillia and the Sun/Pez Sphere are the Same StoneAll you need to look at is the number of years between creation of a Sun Sphere on the Sun and the number of years the Sun Atlamillia can travel, either direction, through time. They're both 10,000 years. Caught in the evil Dark Cloud below Dark Heaven Castle, the Sun Sphere absorbed the evil energy, losing its green stripes and became pure yellow. Like the "lucky" rat, the Sun Sphere absorbed some of the Dark Genie's power.
Alternately, the Sun Atlimaillia is A Sun SphereAgain, see the 10,000 year cycle.
Someone in Dark Cloud 2/Dark Chronicle is a Time LordWith all the time travel, it's bound to happen.
Palm Brinks is a combination of Queens and the Demon ShaftHigh above the ground (Demon Shaft), mostly walled (Queens), and check out the scroll work on the town gate.
Sheriff Blinkhorn is Wilder's descendant
Monica Raybrandt is part genieShe has the same Power-Up Food as Ruby.
Xiao was originally owned by someone who lived in Norune village. Her owner died in the Dark Genie attack.Every time Toan meets her before recruiting her, she is already wearing a collar. Unfortunately, Fairy King Simba was not powerful enough to save her original owner.
Monica Raybrandt is Max's great grandmotherWith the big time pretzel going on, and her stuck in Max's time it makes sense. She has a kid whose kid turns out to be Elena. That'll bridge the 100 year gap, and make her Max's wife and great great grandmother.
Monica2 is The Girl In The StreetAfter the events of Dark Chronicle/Dark Cloud 2, Monica uses a Starglass which returns the user to a time of great significance to them. When Lin's starglass took her to the day Crest was killed, we get evidence of both Lin1 and Lin-A in the same time, granted in different places. The reason people who aren't traveling with you know things is because Monica2 has told them about your adventures on her way to Palm Brinks and the Zelmite Mines.
Toan's time is Before Monica's, but after Max'sJust think about it, You have to do many changes to the landscape to revive Jurak in #2, yet you only have to create a river to revive him in #1. Palm Brinks eventually becomes abandoned (more on that later). Osmond in the first game was not at Luna Lab because it didn't exist yet. (Luna Lab was founded after Shingala brought a huge haul of Luna stones 27 years after his rescue.) Mt. Gundor was demolished somehow (which would explain why you barely see the volcano in Monica's time) and Gundorada workshop was not built yet. Winds from the sea blew sand over to the no longer mountainous area, forming the desert, Muska Lacka was actually just a temporary camp while they were making preparations for Gundorada, and eventually Paznos. Then An earthquake happened to happen right near Gundorada when it was just a foundation, forming the mountain that was carved to create Gundorada. Toan's village was probably a group of settlers that came from Palm Brinks shortly after the end of Dark Chronicle, and they decided to make a settlement in the area they found. The fairy king is probably a mix breed descendants of the Firbits and humans, seeing as he's a fairy but also looks very human. He also has that silly mustache.
Toan and the others NEVER returned to their own timeSeda says he's going to improve the world. He supposedly has amazing magical power even without the Dark Genie. After rebuilding both continents, Seda either creates a fabrication of what Toan and Xiao remember, or makes these places exist earlier.
All four Atlamillia are part of some divine cycle of death and rebirth.Though this can be Jossed easily due to different sources -the Fairy King grants one Atlamillia to Toan, while the other three are suggested to be crafted by the Moon People- hear me out. These Atlamillia all have a predestined function. The green stone -some say it's blue, but it always looked blue-green to me- is the Altamillia of "history", or "records", keeping the fragments of the world together within it. The other three, Red Earth, Blue Moon, Yellow Sun, symbolically represent the events that will lead to the "Star of Obilivion". He who bears the yellow stone gathers them together, and thus the Blue Moon shall fall and the earth with be consumed in the fires of destruction... After all is said and done, the earth is 'reborn' through the Atlamillia of the first game.
The war that Seda fought in was against Alexandra's nationThis theory is explored on the official Dark Cloud wiki under the heading "Dark Cloud History". Because of the Timey-Wimey Ball, it is mentioned as a branch from a timeline.
Gaspard is distantly related to the Fairy King or Seda
The Fairy King is actually CondaHe just changes his name every century or so.
Seda is a Loki ExpySure Seda's not really a trickster. In Norse Mythology most of Loki's children were in someway beneficial. When did that change? When he got it on with Angraboda, a witch. The children from that union were all in some way destroyers: Fenri(r/s) the wolf, Jørmungand the Mittgard Serpent, and Hel(a) the goddess of death and plague. I'm actually surprised it took me this long to think of this guess, after all Seda's Start of Darkness was mixing his blood with that of witches.
