After days of nightmareish exhaustion, one of the marked ones - Norien - revealed through sensitive deduction that the now possessed Franisbel was heading north, to Coerthas. Begrudingly, the group gathered to follow on the tracks of the outwordly, reality-wrecking presence. Its wake was recognizeable, for it laid death and misery wherever it went, its' passage was unmistakable. 
They reached an abandoned, worn-down village in the hostile frozen land. What they found was a sight that would have stuck with them till the end of their days; corpses were piled up on tall pikes like pork chops on skewers, all around the village's perimeter. Just nearby, an insane overweight priest was chanting all kinds of horrors to summon a sickening creature; amidst howls and horrifying screams, the abomination grew as a sewn-together agglomerate of all sentient species' limbs, alongside animals. It was a living terror, screaming with rage and agony.

The group faced it, in a low-drawn battle against the foul creation of an impressive sturdy resilience. The priest seemed immune to all kinds of attacks as well, ravenous and delirious as he was, he moved out of the scene to disappear, and answer the call of his master. 

Following the priest led to an underground location, where a ritual was taking place. The marked members of the Rootless suffered the most vivid nightmares, to the point of feeling mentally crippled. In the gloomy underground, possessed Fran was attempting a ritual with the priest and a pregnant girl known as The Becoming. A ritual of invitation where Atuteran was supplied an "empty" mortal vessel in order to manifest its form and full power in the mortal world. The child had to be willingly offered by the mother and given to him from her arms. Her life force is given in the process as a kind of reverence. With Maya and Norien subjugated by the mark's influence, Dwassyith, Xihsa'li and Kami had to stop the ritual - and it happened barely, and just in time. The Becoming had been stopped, retreating into a temporary defeat and leaving Fran's vessel free to regain its own conscience. 
In an underground prison of the church, the group found Baelser Voranti, the author of the book focused on the legend of Atuteran.
 

The following days were spent in Ishgard, where the group had been stuck under the hammering force of a blizzard. Only after the weather got cleared, they could depart for the final journey to put a stop to this once and for all: Ala Mhigo and the ancient temple of Atuteran was waiting for them. Voranti was set on performing the risky ritual called "The Anchoring".

By reversing the ritual which once created the infernal Voidstone, Baelser hoped he could imbalance its nature and destroy it. Even before they began, things went wrong. Kebbe, being marked, was affected by the Demon and sent into madness. As the ritual began, binding Xihsa'li, Maya, Fran and Baelser himself into a difficult, magical struggle, she attacked with fierce ferocity in order to claim The Voidstone. Even as she was subdued by her mate, Norien  lost her will to the power of the mark.
In a bout of madness, she entered the circle in order to give herself to her God, therefor heralding a second Becoming. As the four mages fiercely struggled with the difficulties of the ritual, the Demon came forth and took her for its own.
The end was near and hopelessness clung to their minds, when Baelser eventually managed to seal the last seal and unmake the stone. As it was destroyed, the Demon was sent spiraling back into the void, but not before it could end Baelser's life.
