Timeline
Current month and day are clear, year is not. I have used letters as a placeholder. A is the farthest back any information is available. (I could determine a range of options based on available data but I do not think that it matters very much.)
I can not personally vouch for any information prior to February 14, B.
December 1(?), A
The sky is filled with too many stars. Inhabitants are told to make wishes to make them fall. Wishes are granted as the stars fall. The problem is cleared up within eight days.
December (?), A
An apparent epidemic of mistletoe, presumably brief.
December 23, A
A blizzard develops. Inhabitants awaken paired inside huts and sharing a blanket, and prevented by shadow/light monsters (also described as ghosts) from leaving. Attempts at fighting the ghosts are only successful if carried out in pairs, single-person attacks "do not stick." The huts are described as barren and lacking in food. (Food was delivered by birds "a few days later.")
December 28, A
The blizzard dissipates.
January (?), B
The Necessities "stabilize their existence."
January 1, B
The sun does not rise and there are fireworks.
January 2, B
Caves with monsters inside appear in the landscape.
January 13, B
Echidna, the owner of the caves, appears and is angry that they have been explored. (Statement involved the word "penetration.")
January 25, B
Inhabitants begin to transform into monsters. The transformation is reversed by "opening our hearts." Hugging is apparently involved.
February 2, B
Inhabitants wake up with red strings attached, leading to plants. (These plants grow into roses later.)
February 14, B
Many people find themselves singing and dancing not of their own will. Catalyst unknown, resolution unknown. Possibly related to a strange scent that got everyone "all touchy-feely." (According to one correspondent.)
February 15, B
Roses that were not cared for become mobile and predatory murderplants. Sol discovers that they are repelled and killed by fire.
February 17, B
Queen refuses to defend inhabitants against murderplants, saying that she can not destroy them because they belong to other people. She makes them sing instead which actually makes the whole ordeal even more crazy
February 22, B
Murderplants destroyed by other roses. Medals distributed to certain people, possibly related.
February 24, B
An employee of the Queen lectures us about not paying proper respect to roses.
March 1, B
A factory appears, producing chocolates which will turn out to be drugged.
March 3, B
The drugs take effect, continue their influence for a week.
The Labyrinth is introduced in response to a murder.
March 11, B
The factory is closed. Investigation reveals useless machinery.
March 14, B
Mutilated animals are discovered. Source remains unknown.
March 21, B
The Queen offers to send people back, but is kidnapped by some of her employees and put into the Labyrinth. The mirrors on the vine shatter temporarily.
March 24, B
The Labyrinth is opened, and many people enter in search of the Queen.
March 30, B
The Queen has been restored and rescinds her promise to return people.
April 2, B
Invitations appear for a ball to be held on April 8.
April 8, B
Available clothing is replaced with formalwear. Unknown things (later revealed to be a variety of pokaman(?)) move in the grass and plants. At sunset, inhabitants are compelled by the pokaman toward the Viridian Pavilion (newly created) for the ball. (It is also discovered that these pokaman can not be caught in a poka ball. This is an unusual thing, apparently.)
April 11, B
At midnight the Queen appears at the Viridian Pavilion behind a barrier and introduces a new stairway. She claims it is to another world. She disappears. (Some explorations to this "world" happen. It is found to be called Antikythera. Somebody here is really geeky.)
April 25, B
At night, robots from Antikythera invade. They are destructive at first but are conscious and respond to training.
May 13, B
Most of the robots return to Antikythera, a few stay in the Gardens. It looks like the ones that stayed were interested in people they interacted with. Possibly they are ambassadors or observers.
June 1, B
After an unexpected month of not much happening the Queen throws a hissy fit because we are not hooking up fast enough and the stars fall out of the sky.
June 7, B
Phantoms of people from people's pasts start showing up and being manipulative assholes in the edges of the Gardens. Also nobody can get to where the magic dirt is.
June 15, B
Someone leaves a stupidly cryptic message on the Vine and refuses to be more specific or helpful. Obviously it is one of the queen's people. It is figured out that people have to go get some special rocks from the magic dirt places and a lot of people go.
June 23, B
Apparently everything is fixed now. It turns out that the queen's employees can not go into the magic dirt places. The people that got the special rocks are given a wish each for their efforts. Also the person talking tries to convince everyone that the queen did not mean to mess everything up and was not trying to hurt anyone, which should be evidence enough that everyone running this place is crazy.
July 10, B
The Queen gives a bullshit apology for messing with everyone's head and then warns that she has a project. Nobody thinks this will end well.
July 15, B
Another new place, the Crimson Pavilion, with another fancy party. The drinks are drugged like the chocolates were (see March B events)
August 5, B
A hurricane appears in the gardens and destroys all buildings except the "necessities" buildings so everyone is forced to go in there or suffer. The Queen is obviously running out of ideas. One of the powers that be claims that it came from "outside."
August ?, B
Date unclear. People start getting into each other's dreams somehow.
August 8, B
The hurricane ends. Dream crossing over continues. People begin to notice strange flowers. Over the next couple of weeks the flowers spread and begin to break apart things, including apparently the magic stuff this place is made of. Extermination efforts begin.
August 19, B
A written message on the Vine gives some kind of cryptic B.S. about branches being better than roots and that's "the source of our problems." Exterminators are given dreamcatchers because this place was not hippie enough before.
September 2, B
A written message on the Vine from a source only identified as "B" appears making strange allegations, mostly about relationships. May be from a resident, but I am including it here because of the timing just in case.
