The Fyndii are an alien race, and the first star-traveling sentients to make contact with humanity. The Fyndii were one of the enemies the Federal Empire faced in the Double War. Fyndii seem to feel almost no race loyalty; their societies are made up of empathically linked "hordes," and each horde is a bitter rival of all the others. Mind-mutes, incapable of linking, are friendless outcasts. The Fyndii rule approximately ninety worlds, generally inward from the worlds colonised by humanity.
Quotes about the Fyndii
"In those days much evil had come upon the seed of Earth, for the children of Bakkalon had abandoned Him to bow to softer gods. So their skies grew dark and upon them from above came the Sons of Hranga with red eyes and demon teeth, and upon them from below came the vast Horde of Fyndii like a cloud of locusts that blotted out the stars. And the worlds flamed, and the children cried out, 'Save us! Save us!'"
Also, in And Seven Times Never Kill Man!, Arik neKrol refers to the Fyndii as being "stick-thin." In The Glass Flower, one of Cyrain's Apostles is a Fyndii mindmute named Tr’k’nn’r, whom she describes as:
"[Singing] to me in a high shrill voice at the edge of human hearing. He loomed above the mall like a stickman in a child’s crude drawing, a stickman three meters tall, excessively jointed, bending in all the wrong places at all the wrong angles, assembled of old bones turned grey as ash by some ancient fire. But the crystalline eyes beneath his brow ridge were fervid as he sang, and fragrant black fluids ran from the bottom of his lipless vertical mouth. His song was of pain and screaming and nerves set a fire, of secrets revealed, of truth dragged steaming and raw from all its hidden crevasses."
In The Stone City, Holt refers to the stars of Fyndii Space as "scattered lights where the Fyndii hordes raised their emblem-sticks."
In A Song for Lya, the telepath Robb claims that the Fyndii "feel emotions so palely that I can scarcely read them at all."
