Though only a child, Ilaan has an innate connection to dreamspace—a gift that has given him wisdom beyond his years and hardened his mind against the indoctrination of the Inspired. He can't control his dreaming, and he rarely grasps the cryptic images he sees, but occasionally he wakes with a vital insight about the present or the future, and he always feels obliged to act. These oracular visions guided him to a local cell of the Unchained, and they might guide him to the PCs. In this way, if the characters are in desperate need of direction, this strangely mature boy might approach them. Once the PCs have encountered Ilaan, he might reach them in the future using the Dream of Contact feat.
It might be that Ilaan's youth has shielded him from the eyes of the Inspired. Or it could be that his "visions" are in fact dreams sent by one of Riedra's overlords, who is using the boy to guide the party down a particular path.
