🌫️ Mist Seas

The oceans of your world are gone. In their place: bottomless basins flooded with toxic, blinding mist — a second world beneath the surface, where light dies, the rain burns, and everything that lives down there has learned to hunt without eyes.

Mist Seas is an atmospheric survival-exploration mod. Descend for riches no continent can offer, build the gear to survive the descent, and decide how much of the deep you're willing to wake up.

🎒 Play it the intended way: our official modpack Mist Seas: Skies of Tomorrow — rebuild civilization in the skies with Create: Aeronautics, and raid the mist for what keeps it flying.

⚠️ Requires GeckoLib · NeoForge · 1.21.1

☠️ The Mist Is the Enemy

• Blinding, suffocating fog. Visibility collapses to a few blocks inside the seas. Without protection the mist chokes, intoxicates and pollutes — and its creatures will find you long before you see them.
• ☔ Acid rain. When storms roll over the seas, the rain dissolves exposed flesh — and fat caustic droplets burst against anything poking above the mist, eating through plank-tier blocks. Bridges and airships over the seas need acid-proof materials or constant repair. The mist itself is shelter: what lives below never feels the rain.
• 🧪 Acid pools pit the deepest seabed dips. They melt almost everything — but that's exactly what makes them useful (read on).
• 😷 Respirators & filters are your first lifeline; niobium auras and the legendary Purified Rose are your endgame peace with the mist.
• 🧭 Mist Compasses and Misty Maps exist because ordinary navigation simply doesn't survive down there.

⛏️ Riches of the Basin

The seabed is the richest mining ground in the world — if you can work blind.

• Every overworld ore — including ores from your other mods, automatically — studs the basin soil.
• 🪱 But the ores are infested. Ember Vermin nest inside ore blocks (modded ones too) without changing the block. Mine the wrong vein and something furious pops out of it.
• 💎 Corrupted Stone-Coral — chorus-like petrified colonies, tinted in flowing color gradients unique to each sea. Harvest their Ore-Buds with any pickaxe and throw them into acid: they dissolve into random raw ores, weighted by true worldgen rarity. Colonies slowly regrow their buds — a renewable, farmable ore source (and contraption-proof: no airship strip-mining).
• 🔮 Niobium, the mist metal: repels the fog in block form, floats on mist as boats, and anchors the purification ritual.

👾 What Hunts in the Fog

• Fungal Pursuer — a swift spore-clad horror that runs prey down by sound.
• Mucus Stalker — an ambush predator with a sonic blast, lurking in the fungal overgrowth.
• 🪱 Ember Vermin — the basin silverfish: ember-veined, ore-nesting, furious when evicted.
• 🦀 Vermin Scavenger — a three-block-tall crusher crab with a bioluminescent purple crystal carapace. Peaceful until struck, it stalks the seabed rapping on ore blocks to shake vermin out — then crushes them in one claw. Drops meat, and very rarely a Crystal Chitin: combine it with a tool in an anvil for Silk Touch.
• 👻 Phantoms are native here — they dive into the mist to smother their burns, and they hunt…
• 🐋 Ghost Narwhals — rare, pale leviathans cruising the open air above the seas, their glowing emerald tusks shedding fog-protection on everything near them. Tame one and ride it. Guard its horn: the mist eats it away, and with it, its protection.
• 🛑 The Mist Warden — a colossal boss sleeping beneath the great crystal spires. Summon it with a wither rose at the Mist-Heart, survive it, and its Mist Rose unlocks the purification ritual that ends the mist's hold on you. All mist creatures fear the Purified Rose — and every one of them burns in open daylight, outside their fog.

🪁 Take to the Skies

• 🪂 The Mist Glider — an Air-Nomad-style glider staff of niobium, phantom membrane and sticks. Right-click in the air and its great fans snap open: elytra flight from either hand, no chestplate slot lost. No durability, no enchantments, no firework boosting — pure gliding. Dyeable like leather armor, folded or flying.
• 🎈 Updraft Bundles — burst four Weightless Sacs (a pursuer drop) bound with string while standing on solid ground: a violent updraft launches you ~60 blocks skyward in seconds. Going up is easy. You brought the glider, right?
• ⛵ Niobium Boats float on the mist itself; misty cartography keeps you found.

🌳 A World Worth Seeing

Two full fungal ecosystems (Mire and Gloom) with complete wood sets, glowing Misty Lights, Ember Lichen veins, dead-sea gardens of stone-coral shifting through living color gradients, crystal spires blazing over the toxic centers — the seas are as beautiful as they are lethal, and the flora itself breathes in slow waves of shade across whole biomes.
