Villains like to live on private islands, where they have a secret base and can carry out their evil experiments in all privacy.
The Caribbean is popular in fiction, but for my purposes it is just too busy. My villain wants to live undisturbed, for decades. To accomplish that, they want to be mostly self-sufficient, after the initial construction is complete. They want to vanish off the map.
A high initial investment is to be expected, and the villain is basically John D. Rockefeller so he has a big purse. But eventually crops must grow there without greenhouses: the more machines necessary to maintain this island, the greater odds one of them breaks and requires a spare part flown in, which makes the island more easily noticed. The islanders should survive with at most one annual shipment of crucial parts, medicine, etc.
I am looking for a real-life island with the following qualifications:
- No (permanent) civilian population. A small military or scientific base is okay; they can be bought out when the island itself is purchased.
- Isolated; far out of sight from any populated places, shipping routes, etc.
- No historical sites that people might want to visit, no strategic value. It should be unremarkable.
- Arable; the soil (possibly imported) and the climate must allow for the cultivation of enough crops to feed the villain, his family, and a few dozen underlings and their families (a hundred people in total).
My current best bet is Macquarie Island, which is not all that hospitable but doesn't regularly freeze over either; and the intense local cloud cover would actually be a useful camouflage from satellites. Is this the best pick or are there better islands?
