☁️ Mine Mine no Mi: Sky Island

Skypiea, as a dimension of its own, for Mine Mine no Mi.

Find a Knock-Up Stream on the floor of the deep ocean, wait for it to erupt, and ride it ten thousand metres up — to the sea of clouds, the Angel Islands, the Upper Yard where the City of Gold was lost and God's priests hold their Ordeals, Birka that Enel burnt, and Weatheria drifting above it all.

⚠️ Mine Mine no Mi's own sky islands no longer generate in the overworld: Skypiea takes their place.

🌊 The way up

Somewhere on the floor of every deep ocean sits a Knock-Up Stream. Every ten minutes it rumbles, then erupts, and the column throws whatever is caught in it into the sky — you, your crew, your boat with everyone aboard. Hold on: you come out in Skypiea, in front of the island's Heaven's Gate.

Coming back is simpler: step off an island, sink through the clouds, and you fall back out above the same stretch of sea.

☁️ Skypiea

• The sea of clouds — translucent, with a swell: you swim in it, sail on it and see the fish under you. Islands only float above the overworld's deep oceans.
• Angel Islands — made of island cloud from top to bottom.
  • Skypiean villages, larger on the larger islands: five kinds of houses, each with its own roof colour, painted shutters and furniture; an amber inn, a coral dial shop, a bandstand, kitchen gardens tilled right into the cloud, a cloud fountain.
  • Skypieans of our own live there, winged, with their hair grown into antennae — and the dial merchant behind his counter.
  • The White Berets police every village from their post: eight faces under one uniform.
  • Angel Beach, where dials wash up on the shore over time, a seafront with the dial workshop and its pier, and White Beret lookouts.
  • Heaven's Gate, and the causeway on to the island.
• Upper Yards — rare, huge islands of the Blue Sea's earth, jungle plains and crags.
  • The Giant Jack, climbable all the way to the Golden Bell — and the chest beneath it.
  • Shandora, the City of Gold — its halls, its stepped temple, and the crypt under the Poneglyph. Small ruins lie scattered through the jungle.
  • The Shandias guard their land with spears, bows, pistols, rifles, shields, burn bazookas and dials. They leave you alone — until you open their chests.
  • Shandia war camps in the clearings, and their hidden village in a pocket of cloud at the island's foot.
  • Sacrificial altars in the jungle, a trail of gilded slabs from one to the next — and, on one Upper Yard in three, the great Sacrificial Altar on its lake of cloud, with no bridge and sky sharks on guard.
  • The Sanctuary of God, Enel's residence, on a summit: a great stair of cloud, the hall with the red roof, the throne and its Thunder Drums — kept by divine soldiers who fight with their dials, and their commander.
• Birka — Enel's homeland, one Angel Island in five: scorched cloud under a veil of ash.
  • In ruins, most of them: a town of pale masonry struck at its heart, its vault laid bare at the bottom of a great crater.
  • Still inhabited, a few: the lightning spared them. A whole town round its temple — the Birkans in their houses, a merchant of Birkan masonry and common dials, a craftsman who always has Flame and Impact Dials, and guards who leave you alone until you steal. The town remembers a thief.
• Weatheria — the weather scientists' island: four tiers of cloud on a great glass bubble, floating over land and sea alike.
  • The scientists' town: Haredas's tower, pinwheel windmills, the observatory's glass sphere, the Weather Ball garden, white stairs and promenades.
  • Haredas teaches the Art of Weather, and the Weather Vendor sells the weather of the Blue Sea below: clear sky, rain or a thunderstorm.
• Milky Roads — roads of milky cloud from each island to its nearest neighbour, over the sea and across the void.

⚔️ The Ordeals of God's priests

Four challenges of Mine Mine no Mi's challenges menu, each in a Standard and a Hard version, each learnt in Skypiea from its stele — an enclosure of stone on the plains of an Upper Yard, round a great poneglyph to rub with paper. An island has two of the four: the others are on other islands.

• The Ordeal of Balls — Satori in his forest of Surprise Clouds, and his Ball Dragon.
• The Ordeal of String — Shura on his bird Fuza, his Heat Javelin, and a forest strung with String Cloud.
• The Ordeal of Swamp — Gedatsu, his Jet Punch, and an arena pitted with Swamp Cloud.
• The Ordeal of Iron — Ohm, his giant dog Holy, and the Iron Cloud.

🛵 Getting around

• The waver — Skypiea's cloud-sea scooter, driven by a Breath Dial: faster than a boat, and it glides on cloud. Craft it, or buy it from the Waver Dealer on the seafront.
• Flying mounts (below), and the Milky Roads on foot.

🐦 Wildlife

• The giant South Bird of the Upper Yards — a living compass: stop, and it turns to face south.
• The Sky Dot Bird (Pierre's kind) and the Three-Jo Bird (Fuza's kind) — flying mounts. Win them over with seeds, saddle them, and fly: the movement keys go the way you look, Jump climbs, Sneak descends. Only their owner can ride them.
• The Cloud Fox (Su's kind) of the Angel Islands — tame it with fish; it follows you and curls up on the cloud.
• The Giant Dog (Holy's kind), rare and huge — tame it with raw meat. It guards you like a wolf, and with a saddle it's a mount.
• In the cloud sea: shoals of Sky Fish leaping out of it, the rare Balloon Sky Fish, the Giant Sky Fish whose fan cuts the surface, and the Sky Lobster on the beaches. A fishing rod works there.

🐺 The predators of the Upper Yards

• The Cloud Wolf — a wolf on two legs, hunting in packs. Brave enough? Cooked meat can tame it.
• The Sky Shark — it swims the air and goes for blood: the wounded draw it from far away.
• The Sky Lamprey — a giant lying in wait under the ground. Come too close and it rises, bites, and holds you in its mouth until someone strikes it hard enough.

💰 Worth the climb

The structures are rare, and they pay: Wooden, Iron and Golden Boxes at the top of the Giant Jack, at the foot of the throne in the Sanctuary of God, on the great Sacrificial Altar and in Birka's vault; now and then in Shandora's crypt; rare dials in the vault and at the craftsman's; smaller finds in the ruins, the Shandias' tipis and Weatheria's chests.

🧱 Blocks to build with

Cloud bricks, cut cloud and cloud glass; Birkan Plaster and Brick, three friezes and a rose window; Shell Tiles in turquoise, coral, amber and lilac; painted Shutters and Doors; Awning Cloth; Milky Cloud; Gilded Stone Bricks; the Weather Cloud that drizzles, snows or blows; and the Sea Cloud Bucket to carry the sea home — it waters cloud farmland.

🧩 Compatibility

• Worldgen mods: Skypiea reads the overworld's own biomes to find the deep oceans and changes nothing in the overworld beyond the geyser. Checked with Terralith and with TerraBlender + Biomes O' Plenty.
• Valkyrien Skies 2 (optional): sail your ship into an erupting Knock-Up Stream and it rises to Skypiea with its crew and floats on the cloud sea. Fall off the edge, and it comes home the same way.
• Other mods and datapacks can use the biome tags inosky:is_skypiea, inosky:is_cloud_sea, inosky:is_angel_island and inosky:is_upper_yard.

⚙️ Configuration

Per world, in serverconfig/inosky-server.toml: the geyser's rhythm, the height you fall back from, how often dials wash up. Operators have /geyser (the nearest geyser and when it erupts) and /geyser now.

Server builders get a creative Knock-Up Stream block to place their own way up, and empty_skypiea = true for a Skypiea with nothing in it but the sky — to build their own.
