The Blue Seas
The fictional ocean Martin calls home — teal water, drifting lantern-isles, and weather that sometimes argues back.
Fiction, clearly labeled. The Blue Seas are an invented setting for Martin Tidewell’s stories. Any resemblance to real waters is coincidence and salt spray.
The shape of the water
The Blue Seas are not blue the way other oceans are blue. Sailors say the water holds the color of a robin’s egg in the shallows and deep indigo past the shelf, and that on windless mornings it turns the exact color of Martin’s coat — which is either poetry or the reason the seas are named so.
The known Blue Seas stretch from the Harbor of Port Mercy in the east — Martin’s home port, all taverns and rope-makers — westward past the Lantern Isles, a drifting chain of low islands lit at night by phosphorescent tide-pools, to the far Glass Calm, a windless mirror of water no chart claims to have crossed twice.
Ports of call
Port Mercy
Home. A crescent harbor with a white-and-blue lighthouse, the Sailor’s Rest tavern, and a chandlery that extends Martin unlimited credit (he has never used it, which the chandler mentions constantly).
Gullhaven
A cliff-top town where the gulls are considered citizens and outvote the harbormaster twice a year. Martin once won a knot-tying contest here against a gull. The gull demanded a rematch.
The Lantern Isles
Not one port but a dozen drifting isles, each lit by natural tide-pool glow. Ships navigate between them by the color of the light. Martin knows every isle’s tint by heart.
Brass Anchorage
A floating market town built on lashed-together hulks, famous for brasswork, strong tea, and gossip. If news travels the Blue Seas, it starts here.
Currents and weather
The great Tidewell Drift — named by fans, not by Martin, who finds the whole thing embarrassing — carries ships westward along the lantern chain. Against it runs the Widow’s Counter, a cold current sailors respect and never whistle at.
Weather in the Blue Seas has opinions. The Squall of Nine Days is a storm that, once a decade, parks itself over the central seas and refuses to move. The Singing Fog off the Lantern Isles hums in harmony — sailors harmonize back, which is how half the shanties were born. And the Glass Calm is the absence of weather entirely: a sea like polished glass, where ships have been known to sit for weeks, and where Martin once sat for eleven days, mending sails and talking to a mistwhale.
What lives here
Mistwhales with lantern-spotted backs, lantern eels that light the night water, gull-citizens of Gullhaven, and — in the Deep Blue past the shelf — something large that the charts mark only with the words “here be patience.” See Creatures of the Blue Seas for the full bestiary.
