Ok if you've read the books of sorrow you know the story if not let me sum it up. So on this planet, the Fundament, there were thousands of species. The weakest, puniest of these species had many factions. One of them was the Osmium Throne. The Osmium King (as it sounds, he was the king of this faction) had 3 daughters. Aurash, Xi Ro, and (I can't remember her original name but later she became Savathûn). These three each had their own nature to them: Aurash wanted to be king was naturally curious and wanted to learn, Xi Ro wanted to be a knight and was naturally brave, the third (later Savathun) was cunning. The traveler appeared and arranged the 52 moons of the Fundament to create a God Wave (a massive wave) to destroy the species on the Fundament. The Osmium faction had mothers (those who made the spawn), the Knights (the soldiers), and the King. One of these mothers was Taox. Taox saw that the Osmium King was weak and betrayed him by going to the rival faction, the Helium Drinkers. The Helium Drinkers invaded and the three sisters escaped on a boat. Savathuns cunning got the three to sea on the Deep where Aurash, the first navigator, led them. Their species had a short life and they realized they were going to die. Long story short they dove to the core of the Deep and made a pact with the Worms (Akka, Eir, Yul) and became immortal so long as they killed using their nature to satisfy the worm spawn inside of them that gives them immortality. They then became Auryx, Savathûn, and Xi Ro became something I can't recall. Auryx then became male Oryx. The siblings created the hive to feed their inner worms as they no longer could kill enough themselves to satisfy the worms growing hunger. So the siblings aren't hive, they created hive. So originally what was their species?
