All things are supposed to return to its shores, including Esmé Squalor's fire dress from The Slippery Slope. The true name of the island is unknown. Count Olaf informally names it "Olaf Land" after seeing it for the first time, and believing that the inhabitants are primitive, thinking they will accept him as king. None of the island's other inhabitants refer to the island as "Olaf Land", and Olaf is actually banished to the coastal shelf by Friday when he attempts to establish himself as king. Ishmael is the island's facilitator but he keeps the secret of V.F.D. from the other islanders. When Bertrand and Beatrice Baudelaire were the leaders of the island, they attempted to create a Utopian society of it. It is the final resting place of Kit Snicket and Count Olaf, and the birthplace of Beatrice Snicket.
It is apparent that Lemony Snicket visited this island on a boat, possibly the Prospero, to gather information about the Baudelaire orphans, as the letter to his editor at the back of The Penultimate Peril is a napkin marked with a picture of a boat.
Inhabitants of The Island are called Islanders. The following people were at one point, or are, Islanders.
The Baudelaire Parents
Beatrice and Bertrand Baudelaire once washed ashore on the island, and they turned the island into a wonderful place where the castaways could still further their study of the world. The island was to act as a place of recuperation for volunteers deeply affected by the schism. They ate wonderful gourmet meals and put to use all of the items that washed up on the coastal shelf. They started many projects, such as a tunnel to Anwhistle Aquatics, and the organization of the largest bookshelf and reading room ever recorded in the series. At the time of their stay on the island, Beatrice Baudelaire was pregnant with Violet.
The most important thing that the Baudelaire parents did on the island was create a hybrid between the large apple tree and horseradishes. This was to be a solution to the threat of the Medusoid Mycelium. However the hybrid plant has proven unsafe for unborn children, hence why Beatrice has never gotten to taste an apple, and why Kit couldn't eat one at the end of The End, effectively sealing her demise in exchange for her daughter's healthy life.
After Ishmael washed up on the island, he began to spread rumors and doubt throughout the island that operating so boisterously would eventually endanger the inhabitants of the island. The Baudelaire parents referred to Ishmael's actions as "fear-mongering". Due to frequent outbursts of concern from Ishmael the construction of a passageway to Anwhistle Aquatics was halted. After persuading the castaways on the island of the need for more policies to keep themselves safe, and to keep treachery from washing up on the shores, the values of the Baudelaire parents were abandoned, and those in favor of their teachings left the island.
After being appointed facilitator, Ishmael kept all islanders away from the arboretum, where he stored the mounds of objects that wash up on the island, not permitting the castaways to use most of them. He would not even allow them to use the kitchen to prepare food, and all the meals served on the island during his reign as facilitator were very bland. He changed the uniform of the island to white robes, and he began serving the islanders fermented coconut milk to keep them drowsy and lethargic (as the concoction is an opiate), so that no one will want to challenge his authority over the islanders.
The coastal shelf is a landform onto which the Baudelaires and Count Olaf are deposited after they have survived a violent storm. The shelf is littered with junk as discarded objects from everywhere wash-up on the island; it is said that everything eventually washes up on the island. The Baudelaires are discovered by a six or seven year-old girl named Friday, who takes them to a colony of castaways on a nearby island, leaving Olaf because she thinks he's rude.
After every storm, the islanders search the shelf for wreckage that might be useful. Such a wide variety of things can be found it is said that everything eventually ends up on the island's shores. In the second chapter of The End, Lemony expounds on some of the things that has washed up on the shores:
[...]and other objects that might have been from the boats' cargo, including shatter lanterns, smashed barrels, soaked documents, and the ripped remains from all sorts of clothing, form top hats to roller skates. There was an old fashioned typewriter leaning against a large, ornate bird cage, with a family of guppies wriggling through its keys. There was a large, brass cannon, with a large crab clawing its way out of the barrel, and there was a hopelessly torn net caught in the blades of a propeller.
Many objects that wash up on the shore are considered weapons.
The Arboretum is located inside of the giant apple tree on the opposite side of the island from Ishmael's colonists. It is a large living space, complete with a kitchen, reading room, bookshelves and other facilities to make life more easy for those on the island. Before Ishmael became the facilitator for the island, the Baudelaire parents were the facilitators, and they wanted to use all of the items that wash up on the coastal shelf as a way to educate those on the island. The Arboretum was supposed to also house a tunnel passage way from the underground of the island to Anwhistle Aquatics, one of the safe places of V.F.D. and an underwater archive that housed copies of the organization's information, which was to be then sent to Dewey Denouement in his secret libary. The Arboretum is also the home of the large commonplace book, A Series of Unfortunate Events, in which all of those who have washed up on the island chronicle a bit of their history as well as entries on their stay on the island within.
