Here's my [tentative] build.
How did you get here?
The Unbeaten Path, which is more likely to happen to me, as I like taking walks alone to ponder writing ideas.
Medium-sized, Floating Archipelago
(2-3 Environments, 2-5 Special Locations)
Three main islands in the sky, connected by a network of bridges and aqueducts, and orbited by several smaller islands whose environments are determined by the mainlands to which they are closest.
Island 1 "Roca": Hilly Hinterlands
Island 2 "Arba": Wild Woods
Island 3 "Cuva": Curious Caverns
[Externally, Cuva is an unremarkable mass of mossy rock with few entrances. The goods are within.]
Roca: Polar (The "tallest" and highest island)
Arba: Temperate (The "middle" island)
Cuva: Temperate (The "bottom" and lowest island)
[It says that I can die on the Island, but prisoners are serving billions of years here.
Therefore I must conclude...
1) The narrator is messing with me.
2) You live from young to old, die, and then respawn, unless you are killed purposely.
OR 3) You don't age, but you are not immortal; you will respawn if killed.]
Roca: Lonely Lighthouse (Rocky Pier)
Arba: Uninhabited House (Outdoor Bath), Pristine Chapel (Antediluvian Temple), Abandoned Home (Well-worn Roads)
Cuva: Eerie Tunnel (Waterworks)
Acuity: More capable
Perks: Heroic, Understanding, Leverage (Sword)
Drawbacks: Secrets. The vagueness of this drawback makes it at least seem to be the least troublesome, but I must assume there to be some subtle danger about it, particularly if I indulge in a dream when I should be sober. Other than this, I have no desire to affect the minds of other people, or give enemies any more of an edge against me.
- Hiroko question.
If she doesn't need to eat, nor produce waste, can she still reproduce? The text says nothing about her being human or not, but it sounds like she is either an altered human or an otherworldly creature. If she is human and can reproduce, then perhaps more ideal.
- Kalyani is my choice if the Green Geezer tells me Hiroko is not human/unable to reproduce.
Items & Equipment...
If she is generally passive, I might try to make peace with her. If she is able to read minds, she will find that my intentions are pure.
[I don't quite understand the need for a Grail that extends your lifespan if you and your waifu are meant to serve billions of years as prisoners on the island. If I don't get an answer for this, I'm just going to ignore that part of the flavortext.]
Rene (Abandoned Home)
I will not suffer a witch to live. If there can be no peace, I will destroy her.
The Three Sisters (Abandoned Home)
The mask is too dangerous to keep. If I am forced to dispatch the sisters, I will destroy it.
Dire Wolf (Well-worn Roads)
I don't have a guilty conscience, and I don't think my supposed waifu will have one, either. But if that is what prompts the Dire Wolf to attack, I would try to doubly make sure we can clear ourselves. I can't imagine it being that hard, though.
The rewards from the more dangerous enemies are tempting, but I wouldn't want to endanger everyone on the island for a selfish whim. It would be different if I had no choice, but since the choice is given to me, I will not put others in the way of some world-ending colossus. These seem like the most manageable threats for the layout I've chosen, given my personal set of skills and attributes.
Unburdened Unicorn (Wild Woods)
It is regrettable I may never see this creature, but if it desires to be alone, who am I to argue?
Perhaps it will find a friend in my wife, or any of our daughters. But if not, so be it.
Furry Force (Hilly Hinterland)
I might try to win them over with gifts and fair speeches. But if my kindness is rejected, I already planned to establish my home in Arba, the middle island, which is a bit of a hike away from Roca, the Hinterland, and the Lonely Lighthouse might repel them by its very existence if we need a "home away from home".
Elusive Elves (Curious Caverns)
I hadn't planned for this, but having both Secrets and Understanding might give me a strong leg on these beings. I gladly welcome new friends.
Sagacious Slime (Waterworks+Curious Caverns)
Another unprecedented outcome, given the choices I made prior to this section.
If we are able to keep the peace with this creature, that would be a fine outcome. Seeing as she has few actual needs, I would hope she has no reason to attack us. The other risk of disaster, I suppose, would be the result of her low intelligence. There must be some way to prevent her from getting in the house, if she is ever tempted to follow me or the waifu away from her home. However, I would much prefer not to make her feel unwelcome, if I can effectively communicate the boundaries I desire from her, for the safety of my wife and children.
I have my suspicions, but my default setting is to seek peace with all men.
I don't know how long my sentence is, but I have to assume it's about as long as the other prisoners'. If I have a reason to leave, I will, but I might try to learn from him, and find some new things to do, if I can't return to my old home (and my own time, several billion years ago I guess).
I don't exactly have an idea as to what I CAN do after the sentence is served... so I will make do.
