Indurane was a Changeling and a Founder of the Dominion. Indurane was given his name by Odo, which means "ancient" in the Bajoran language.
In 2376, Indurane revealed the truth as to why the Changelings had sent 100 of their infants out into the galaxy to Odo and Laas - who were the first of the Hundred to return home to the Great Link. Indurane explained that the Great Link and all Changelings were created at once by a god-like being known as the Progenitor. There were no 'infant' Changelings, only Changelings that had not separated from the Link and begun to learn. This was the reason why Changelings had such restrictions on harming one another - with each Changeling death, the species was brought that much closer to extinction. The Great Link was hoping to attract the attention of the Progenitor by sending out the Hundred, so that it could be lured back and replenish the species. Indurane had knowledge of the Ascendants and was able to use his shapeshifting abilities to appear as one. (DS9 - Worlds of Star Trek: Deep Space Nine novel: The Dominion: Olympus Descending)
