Avatar of Yncarne
The Yncarne is the Avatar of the newly awakened Eldar God Ynnead. His awakening was the first step to the Seventh Path, a method of awakening Ynnead without sacrificing the entire Eldar race. However, his birth required the sacrifice of many souls within Biel-Tan's Infinity Circuit. Nonetheless, the leader of the Ynnari, Yvraine, successfully undertook the ritual and Yncarne was able to save Biel-tan's remaining Infinity Circuit from The Masque.
After its birth, Yncarne fought alongside the Ynnari on their quest for the Crone Swords. However, while on the way to Kalisus, the Ynnari were assailed by the Prodigal Sons.
The Prodigal Sons are a warband of Chaos Space Marines dedicated to the service of Tzeentch, the Changer of Ways. The members of this warband are composed of a cabal of powerful Chaos Sorcerers who have chosen to follow the potent Chaos Sorcerer Ahriman in exile from the larger Thousand Sons Traitor Legion out of their desire to seek out knowledge from Tzeentch and to gain some of his power for themselves. Though successful in fighting off the Chaos Space Marines, Yncarne went missing after the battle.
In battle, The Yncarne wields the Crone Sword Vilith-zhar.
