Tuilindo was a Noldo of Valinórë, the swiftest of all elves to run and leap and the surest of all the archers of the Eldalië. He marched across the Helcaraxë with the Host of Ñolofinwë, and upon their arrival in Beleriand he took the name Duilin and was appointed as a counselor to High King Fingolfin, where he worked closely with his colleague Egalmoth, another skilled archer. Great love grew between them, and they were wed in the thirty-fifth year of the Sun, at which time they entered the court of their friend Turukáno at Nevrast.
When Turukáno began to order his new kingdom of Ondolindë, he offered positions of lordship to both Egalmoth and Duilin, which they were glad to accept. Upon removing to the isolated valley of Tumladen, Duilin returned to his previous name of Tuilindo to spite Thingol’s ban upon Quenya, though Egalmoth chose to retain his Sindarin name.
In Ondolindë, Tuilindo became the Lord of the House of the Swallow. His folk were great archers like himself, wearing fans of feathers upon their helms and bearing the emblem of an arrowhead. The majority of his folk were Noldorin in origin, though many had been born on the eastern shores after the Flight from Valinor.
One of Tuilindo’s closest advisors and greatest captains was Cútasar, a sharp-tongued hunter and the mother of Ezellë, wife of Makalaurë Fëanárion. In Valinor she and her daughter’s law-father clashed often, especially over the pronunciation of her name: he insisted it ought to be pronounced Cútaþar, much to her chagrin, and when it was Sindarized to Cútathren she despised that Fëanáro’s þorn had forced its way into her name. Thus she was glad to return to being Cútasar in the safety of Ondolindë’s walls where Thingol’s ban upon Quenya could not touch her.
As she detested Fëanáro, Cútasar and her wife Poldamaitë had chosen to join themselves to the Host of Ñolofinwë and thus were forced to cross the Helcaraxë, where she befriended Tuilindo. Poldamaitë was a smith and not inclined to the skillsets of the House of the Swallow, and over the years conflict grew between the couple, eventually resulting in their separation and Poldamaitë’s defection to the House of the Mole when Turukáno granted a lordship to his nephew Maeglin.
Amid the chaos of Gondolin’s fall, Tuilindo fought with his husband upon the battlements where he was struck by a fiery bolt from a Balrog and fell off the walls to his death. At the loss of her lord, Cútasar joined Egalmoth and with him rallied the folk of the Swallow to descend into the city and face the Enemy head on. They fought their way through the alleys, defeating every band of enemies they encountered and rescuing many captives and leading them to the Square of the King.
It was there that Cútasar joined in battle with Poldamaitë her estranged wife. The House of the Mole was divided among itself, some following Maeglin into betrayal and others rebuking him, and Cútasar was uncertain where Poldamaitë’s loyalties lay. They clashed together with blades as they had with words for so many years, but through the din of battle Poldamaitë managed to communicate that she still fought for Gondolin and the King. At long last they put their feud aside, fighting back to back against a common enemy up until the moment of their deaths when Gothmog, Lord of Balrogs, broke into the square and consumed them both in a blaze of fire.
Though Tuilindo and Cútasar both were lost, many of the House of the Swallow escaped with Egalmoth through Idril’s secret way. Among these survivors was Roitaro, a young nér born in Gondolin whose parents were lost in the Fall. Weary and grieving, he hung behind as the exiles made their way into the wild, and thus bore witness to Lord Glorfindel’s battle with the Balrog. He rushed forth to alert Lord Tuor of the danger, though it was too late for anyone to save Glorfindel from his demise.
Roitaro settled at the mouths of Sirion with the other Gondolindrim, mingling with exiles from the other fallen kingdoms. He had never before seen the sea, and was now enchanted by it, nearly as much as the young lord Eärendil. His new lover, a survivor of the Ruin of Doriath, gave him the name Aerandir, and in turn Aerandir named him Falathar; not long after, the two invited their dear friend Erellont to join their relationship, and together the three of them aided Círdan and Eärendil in the construction of Vingilótë. Aerandir, Falathar, and Erellont became Eärendil’s companions on his voyages, accompanying him even to Valinor, where they made a home in Alqualondë.
In time Aerandir would reunite with his lord when Tuilindo was returned from the depths of Mandos. Tuilindo would return to his husband Egalmoth at last, and alongside Ezellë who had never left Aman would witness the rededication of Cútasar and Poldamaitë’s vows to one another in their second lives, their family at last made whole.
