Overview
Merfolk are the scaled kin of the reef. They trade in pearls, they consider the reef a promise the sea keeps for them, and they remember every pearl they have ever grown.
Habitat
Merfolk live in Coral Throne, a living reef city of coral architecture and pearl trade. They need three things: a water warm enough to keep the coral honest, a reef wide enough to hold the throne, and a surface that is worth the trade. They are settled in thrones around the living reef, with trading-lines across the mapped current; a merfolk who has not traded a pearl in a season is called "the one who forgot the reef."
Appearance
The merfolk silhouette is the long, low, scaled shape — heavy through the crest-fin and tail, with the head sitting a little too high on the neck, like a word that is waiting for a trade. Males run 1.83 m to 2.13 m from crown to tail-tip, heavy through the crest-fin and tail with a thick blue-green scale and a low, barked voice; they are the wall, the first strike, and the ones who guard the reef. Females run 1.83 m, leaner and quicker, with a thinner scale and a longer memory; they are the pearl-keepers, the ones whose scales hold the reef's memory, and the ones whose nod is the trade. The base scale is a thick, wet, glistening blue-green, the color of deep reef-water seen through a bright glass, with a faint pattern of deeper, sea-green bands along the spine and a clean, deliberate bone-white at the fin-edge that is the merfolk line's most persistent claim. The eyes are a pale, washed-out sea-green, large for the head, with a slow, deliberate blink and a depth that makes them look like they are reading the current — and in most cases, they are, and the reading is the point. The head is the mark: a long, narrow skull with a crest-fin of thick blue-green running from the crown to the nape, and a pair of true, pointed ears set high on the head in the same blue-green as the scale. The pearls are the mark — grown in the scale, always clean, and always traded, the merfolk line's most persistent claim. Males carry the line in the crest-fin and the tail; females in the scale and the memory. Elders are marked by a scale gone a deep, dull sea-slate and a crest gone pale silver — an old merfolk swims slower and holds the pearl longer. Everyday wear: a wrap of woven kelp at the waist, a single pearl at the throat, and no armor, because the scale is the armor and the trade is the home.
Behavior
Disposition: social, clannish, territorial, honor-bound. In peace, merfolk are watchful, deliberate, and absolutely certain of the reef — they have the coral, and they let the surface know it. In war they fight as the reef fights: the wall first, the strike second, the patient, precise holding of the current third. Strangers on the surface are either a trade or a mistake, and the mistake is the one the reef remembers. The social unit is the throne, 50–200 strong, around the living reef — no throne follows a guard, it follows the pearl whose scale holds the most memory. Two signature quirks: a merfolk who is being lied to will not call it out — they will simply grow a pearl in the scale and wait, because the growing is the point. And they keep the pearl for a lifetime: a pearl the throne has grown is a debt, and the debt is paid in trade.
Warfare & Markings
Tactics: the wall of the reef — the merfolk line does not fight in the open current; it fights as the reef fights, with the wall, the strike, and the long, deliberate patience of the one who has already grown the pearl. Armor: scale, by choice — the natural scale is the armor, and a merfolk who wears metal has already decided the reef is not enough. Weapons: the coral-blade, the kelp-snare that is not a weapon but is used like one, and the current that is not a weapon but is used like one. War markings: the Pearl-Notch, a deliberate chip in the left claw for every trade kept, worn as a record of the long reef; the Crest-Knot, a single knot in the crest-fin for every throne oath kept, in sea-green; and the Reef-Brand, a small, deliberate mark on the inner wrist — the first pearl the wearer ever grew, worn as a mark of the beginning. Post-battle: the dead are carried to the Coral Throne, their names spoken over the reef, and their blades laid across the coral — a merfolk buried without their pearl is buried as a surface.
Magic Alignment
Primary domain: enchantment — merfolk magic is the will, the trade, the patient, precise shaping of the current across the reef. Secondaries: conjuration and wild. Named inborns: Current-Sense (a merfolk can feel the current's mood the way a sailor feels the wind), Reef-Sight (a merfolk sees in the deep the way a human sees in the light, and the seeing is not a choice), Pearl-Carry (a merfolk's pearl carries the reef's memory across the throne, and the carrying is not a choice). Signature power: the Pearl Word — a merfolk can speak a word in the reef tongue and let it land on a pearl, and the pearl will keep the word until the trade is done. Limitation: merfolk magic is spent on the reef; a merfolk who has spent their pearl word must sit in the dry dark for one day, and the day is the worst one of the throne.
Religion
Merfolk keep Lysara, the Sweet Poison as their primary god — the enchantment, the will, the promise that is the reef's own law. The reef is Lysara's garden, and the merfolk is the garden's pearl. Priestly class: the Pearl-Keeper, who keeps the reef-temple and speaks the trade at every rite. Heresy is not blasphemy — it is a word broken in the throne, and there is no rite for that one; the throne simply stops growing the pearl with the breaker.
Society
Thrones of 50–200, led by the Pearl-Keeper, rank decided by the pearl — whose scale holds the most memory. Rank is never inherited, it is grown: a pup whose first pearl closes clean can outrun its own pearl-keeper before the season turns, and the outrunning is the whole of the law, because the reef does not care about the blood, it cares about the memory. The thrones keep a pearl-shelf in the coral — a single row of hollows where an outsider's name is grown while the trade is open, and the growing is the whole of the courtesy, because a merfolk who grows your name has already decided you are a trade worth keeping, and a merfolk who does not grow it has already decided the reef is not enough. Outsiders on the surface are either a trade or a mistake, and the mistake is the one the reef remembers — a mistake that breaks a pearl is remembered until the pearl is kept, and the keeping is the whole of the apology, because an apology that is not kept is not an apology, it is a word, and a word is not in the reef. Two rules hold in the throne: a pearl is not broken, and a trade is not refused — the first because the breaking is the whole of the heresy, and the second because the refusing is the whole of the war, and a trade refused is a trade the sea does not return.
Home
They live in Coral Throne, a living reef city of coral architecture and pearl trade.
Relations
The "the reef is the only honest promise" faction — and the keeping of the pearl is the whole of the peace. The Selkies of the mirror trade at the reef-mouth — the selkie keeps the drown and the merfolk keeps the pearl, and the two are the same bargain seen from two seasons, because a selkie that has been traded is a selkie that has been paid, and the paying is the whole of the peace. The Kelpies of the mirror do not enter the reef at all, and the not-entering is the whole of the respect, because the kelpie keeps the mirror and the reef keeps the pearl, and the two have learned that a mirror that is not traded in is a mirror that is not a debt. The Deep Ones of the drag-rites are either a trade or a mistake, and the mistake is the one the reef remembers — a deep one that has broken a pearl has already decided the reef is its, and the deciding is the whole of the offense, because the deep one keeps the drag and the merfolk keeps the pearl, and the two are the same water seen from two seasons. The Dregmaw of the trench raid the outer thrones, and the raiding is the whole of the distance, because the dregmaw keeps the trench and the merfolk keeps the reef, and the two have learned that a reef that is not guarded is a reef that is not a throne. The Kraken of the deep is the season the thrones do not talk about: twice a year the sea is the kraken's, the pearls come down, and the thrones sit in the dry dark, which is the one thing a merfolk finds worse than the drag. The surface-folk of The Forgotten buy the pearl-work — a pearl for a road kept quiet, the same trade-price, grown. Uaellaen keeps a page of the reef in the wiki — the pearl-shelf, the pearl word, the trade that is not a trade — and the keeping is the whole of the record, because the camp has learned that a merfolk who has been written about is a merfolk who has been traded for, and the trading-for is the whole of the welcome.
In the Story
In the current story, the merfolk are the pearl under the camp — the reef Uaellaen writes about when the trade is the only law. The Forgotten buy the pearl-work at the reef-mouth, and the trade has held for two seasons. This season a pearl-shelf was found in the coral with a name in it that no throne in the reef grew — a name that is not in the reef's memory, and the not-memory is the whole of the warning, because the reef keeps its pearls and the pearls do not lie. The name is the one the camp has not been shown, and the showing is the trade, and the trade is the whole of the story.
You swim in our reef and you make a sound. Good. Now we know where you are, and you have made our pearl's choice for us. The price is a pearl. You have one to give, or you are already a find. — Pearl-Keeper Nereus the Blue
