Robin Hobb towards the end of the "Realm of the Elderlings" series called a group of dragons something and I can't for the life of me remember what it was or find it in said books or online. Anyone know what it was?
One at a time, the other great serpents heaved their long bodies free of clinging muck and outgrown skin [...] joining in the tangle's dance.
Ship of Magic - Prologue: The Tangle
Almost immediately, she sensed that the ship did not wish her to be there but She Who Remembers felt no compunction about remaining. Her duty was to the tangle of serpents she had awakened. If the ship were a danger to them, she would discover it.
Ship of Destiny - Chapter 15: Serpent Ship
Maulkin is the leader of a tangle of serpents. His tangle is the last one, and the only tangle who makes it up the river to start the process of turning into a dragon.
In Blood of dragons, a sailor from Chalced called them a Flock when a group of dragons attacks their boats. While not mentioned by Thymara or Elise, it is mentioned toward the end of the Rain Wild Chronicles, if not the end of the full Realm of the Elderling series. I'm listening to the audio book, so i can only state it occurs roughly in the middle of the book, somewhere about halfway though CD 7 of 13.
