Campaign Overview
In an age when the sky itself has become a vast ocean of floating isles—shards of cosmic wreckage scattered like stars fallen to earth—brave captains and daring crews stake their lives on the shifting tides of the Shattered Sea. You are among those daring few called to chart unmapped currents, salvage alien relics, and unravel the enigma of a legendary comet said to grant a single, universe-changing wish. From the Port of Radiant Star, where smugglers traffic in star-metal and clandestine cults whisper of cosmic horrors beyond comprehension, to the mold-encrusted caves of the Floating Isle of Ashen Leech, where blood-thirsty vines drain arcane energies and ancient pirate fortresses lie in ruin, every new horizon holds danger and wonder.
Guided by prophetic half-elf Captain Mira Solara, scholars like Old Magister Rheon, and the cryptic Avatar known as the Star-Eidolon, you will sail amidst asteroid storms, negotiate tense pacts with sky-pirates and merfolk druids, and confront cosmic aberrations that defy mortal logic. You will uncover relics from crashed starships—astrolabes that chart celestial alignments, comet shards that pulse with life, and living crystal intelligences that speak in alien tongues. Along the way, mighty factions vie for control of these powers: the marauding Starbound Corsairs, the occultist Voidseekers, and the stalwart Celestial Wardens. Each offers uncertain alliances or unequivocal hostility, testing your diplomatic and martial resolve.
As your airship slices through phosphorescent mists toward the coral-spined Celestial Reef, the final crucible awaits: the Wishfall Crater, rimmed with obsidian archways and guarded by spectral comet avatars. Here, you must align alien glyphs, repel cultist uprisings, and prove yourselves worthy in a trial that transcends mere combat. Succeed, and the comet’s radiant light answers your deepest longing—whether salvation for a crushed kingdom, vengeance against a cosmic foe, or the power to reshape reality itself.
Prepare to master wind-sails attuned to astral currents, command your crew through skyship skirmishes, solve ancient puzzles of alien origin, and face horrors from beyond the veil of space. The stars may have fallen, but from their ruins, legends are forged. Will your names be written among the constellations? Your voyage begins now.
Starting Location
Port of Radiant Star
Secrets
- A guard captain is secretly a Voidseer cultist plotting to sabotage your ship.
- An underground tunnel leads to the vault from the shipyard and can be discovered with a successful Investigation.
- A board in the tavern’s back room lists secret bounties keyed to coordinates of starfallen isles.
Key Locations
The Celestial Dockyard
A grand shipyard built on floating timber platforms reinforced with fragments of starstone. Each berth glows faintly, energized by residual cosmic magic. Shipwrights and artificers labor around basalt pillars to fit hulls with wind sails enchanted to harness astral currents. Cranes shaped like cosmic leviathans hoist hull sections bathed in azure starlight. The air smells of salt, iron, and ozone. At night, bioluminescent plankton swirl beneath the decks, giving an otherworldly glow. Captains gather here to gossip, bargain for passage, or recruit crew for daring voyages. Farther in, hidden beneath false flooring, lie vaults of illicit cargo and contraband starlight fragments.
Additional Notes
DM may introduce a hidden ledger listing pirate contracts. A secret back tunnel connects to the undercity of smugglers; discovery triggers a chase encounter.
The Starfall Tavern
A rickety two-story establishment patched together from salvaged hulls of skyships that crashed into the bay. Inside, tables are carved from driftwood with star-metal inlays. Neon globs of bioluminescent fungi line the rafters. Sailors and sky-pirates swap tall tales over mugs of cosmic rum brewed with starwater. A trio of sisters known as the Moonsong Bards perform haunting tunes that echo like distant comets. Rumors swirl about a hidden cellar where Captain Ironhook conducts clandestine auctions of alien relics. Secret messages are passed in frothy mugs via encoded patterns in foam. Occasional brawls break out under strobe flashes of glass chandeliers.
Additional Notes
Underneath a trapdoor lies a black-market auction house. The barkeep knows more about the comet’s cycle than she admits.
The Astral Lighthouse
A towering spire of white marble and starstone perched on a jagged promontory. Its beacon is a swirling orb of pure cosmic energy that guides airships safely through stormy starfalls. Inside, a narrow spiral staircase leads past murals that depict celestial phenomena, sky-beasts, and the mythical comet’s passage. At the top, an observatory chamber houses an oversized telescope of brass and crystal lenses. Keepers record patterns of drifting meteor shards to predict floating isle movements. Whispered legends say one of the murals hides a map to the Starfall Crater.
Additional Notes
One mural panel can slide open, revealing a secret chamber with an alien codex written in glowing symbols.
The Hidden Star Vault
Concealed beneath the city’s central plaza behind an illusionary fountain lies this reinforced vault hewn from pure star-metal. The vault door is etched with constellations that must be aligned to open. Inside are shelves crammed with cosmic artifacts: fossilized comet shards, alien computing spheres, star-forged blades, and capsules of trapped nebula gas. Magical wards hum with energy to repel intruders. Archival scrolls detail ancient starfall events and mention a legendary wish-granting comet. Rumor has it the vault’s original architect left behind a coded blueprint to a larger alien starship buried on the isles.
Additional Notes
Unlocking requires a three-part constellation key hidden across town. DM can scatter clues among NPCs.
The Captains' Quarter
A gated enclave of elegant villas built on raised platforms over the water. Each villa boasts its own airship mooring point and personalized windsails etched with family crests. Officers of the Royal Skyfleet, wealthy merchants, and terraforming magnates live here. Marble statues of historical explorers gaze outward toward the horizon. Servants in crisp uniforms deliver messages and star-charts. The Quarter is patrolled by sky-marshals to thwart espionage. Rumor holds that one villa hosts a clandestine star-court where powerful captains broker alliances, betray rivals, and exchange alien relics.
Additional Notes
A hidden meeting chamber beneath one villa can host clandestine roleplay; perfect for secret negotiations or ambush encounters.
The Shattered Sea
Secrets
- An underwater hatch at the Sunken Spire leads to a living star-statue. Rumors of an elemental nexus beneath the Radiant Atoll. A pirate warband uses the Ashen Leech Isle to harvest starblood for voodoo rituals.
Key Locations
Floating Isle of Ashen Leech
A dark basalt plateau covered with thick black moss and pulsing crimson leech-vines that cling to anything living. Pools of stagnant water reflect the blood-red sky. Ruins of an alien anchorage bear strange glyphs warning of a vengeful star-entity. The leech-vines feed on magical energy; spellcasters risk extraction if vines latch on. Beneath the mossy surface, tunnels lead to an obsidian sarcophagus rumored to house a slumbering starspawn.
Additional Notes
Magical detection spells malfunction around leech fields. DM can impose spellcasting concentration checks when near vines.
Sunken Spire
Half-submerged among shallow seas, this sleek, spire-like tower of starstone rises from a circular reef. Corridors etched with constellations wind around its core. Submersible airlocks allow divers to explore flooded galleries of alien machinery. A central chamber houses an inert celestial engine that once powered an ancient vessel. You can restart parts of it to create temporary wind currents or trigger defense drones still dormant. Echoes of a distress transmission loop every dawn.
Additional Notes
If activated fully, the engine yields a one-hour astral wind corridor beneficial for fast travel.
The Radiant Atoll
A ring of sunlit islets covered with golden grass that glows softly under starlight. In the center lies a calm lagoon filled with starwater lilies. At dusk, the lilies’ petals open to reveal crystalline seeds said to be fragments of the wish-comet. Druids of an alien order once guarded the atoll, leaving behind stone circles that harness solar and celestial magic. Across the sands, you find diaries of a lost expedition that glimpsed the comet’s cosmic true form.
Additional Notes
Harvesting lilies requires a DC 15 Nature check. Success yields seeds; failure triggers sand wasp swarm.
The Celestial Reef
Secrets
- Beneath the Heart’s well lies a sealed vault holding the comet’s living core fragment. A hidden eclipsed glyph chamber links to the Void between stars. Star-Eidolon was once a comet’s conscious essence longing to be freed.
Key Locations
Obsidian Observatory
Perched on a high reef spire, this darkened observatory of polished obsidian overlooks the Wishfall Crater. Telescopes of alien design track astral currents and map meteor storms. Inside, a circular star-map embedded in the floor can rotate to chart comet trajectories. A semi-sentient crystal AI called the Star-Eidolon offers cryptic guidance to those who answer its riddles. Outside, terraces hold containment cages for captured sky-serpents used to power observatory enchantments.
Additional Notes
Star-Eidolon can grant a boon if correctly answered three riddles; failures summon protective constructs.
Heart of the Reef
A central gathering isle covered with twisted star-corals that pulse to cosmic rhythms. Stone altars carved with alien runes stand in a spiral pattern around a natural well of starwater. At high tide, bioluminescent currents converge here to form a living constellation reflecting the comet’s path. Pilgrims carve sigils into coral for blessings. Guardians crafted from living star-coral patrol silently, attacking intruders with resonant sonic blasts.
Additional Notes
Coral guardians regenerate every dawn; DC 15 Nature or Religion to pacify them temporarily.
Cometfall Crater
The immense impact basin where the comet’s core buried itself millennia ago. The crater glows with pale blue luminescence from the embedded star-metal core. Alien glyphs etched into the rim form a ritual chamber to invoke the comet’s wish. Ghostly echoes of past rites drift in the air. Twisted rock spines point inward like the teeth of a maw. Within the core’s fractured remains lurk cosmic beings bound by ancient covenant, awaiting a worthy supplicant.
Additional Notes
Ritual requires aligning glyphs precisely at midnight; failure risks attracting a cosmic horror.
