Despite the Jedi Council's best efforts, only a little is known of the so-called Children of the Emperor. Infants of all species taken before the Sith Emperor, the children are infused with the Emperor's strength, sharing some measure of his thoughts and power for the rest of their lives. They become the Emperor's eyes and ears, and‒should the Emperor focus his presence upon them‒his puppets. It is believed that the children have some way to hide their dark presence from Jedi senses, meaning they can exist undetected within the Republic.
The position of the Children of the Emperor within the Sith hierarchy is unclear. Few Sith appear to even know of their existence, and Sith who investigate rumors of the children have been known to disappear without a trace. Since the Emperor would not go to such elaborate lengths simply to create infiltrators in the Republic, the true purpose behind the children remains a mystery.
