The Godborn

The Godborn follows The Twilight War Trilogy and was planned as the first novel in the Cycle of Night trilogy. Now, the book was published in the "The Sundering" Series, and Paul S. Kemp has stated that it is a stand-alone that tells the whole story he intended to write in the "Cycle of Night" Trilogy.Mephistopheles

"The shadow legacy of Erevis Cale lives on even as his old foe Mephistopheles seeks to stamp it out at any cost. Cale’s son Vasen—unmoored in time by the god Mask—has thus far been shielded from the archdevil’s dark schemes, alone among the servants of the Lord of Light who have raised him since birth. ... At the crossroads of divine intrigue and mortal destiny, unlikely heroes unite to thwart the powers of shadow and hell, and the sundering of worlds is set on its course."

Summary
Putting the pieces into place, Mask had sent Varra, the lover of Erevis Cale and pregnant with his child, into the future past the Spellplague. Varra is found by Derreg, son of Regg and brought to safety only to deliver her child, Vasen, and then die during childbirth.

Vasen is raised under the faith of the newly revealed Amaunator, as a paladin. He lived his life as an escort to the faithful of Amaunator to The Abbey of the Rose, a temple veiled from the Shadovar that dominated Sembia. He also acted as protector to The Oracle, the simple son of Abelar Corrinthal. During an escort of pilgrims out of the valley, The Oracle sends away everyone, knowing the fate about to befall everyone.

Along with Orsin, a shadowalker that was accompanying the pilgrims, Vasen investigates signs of a struggle, only to find a village slaughtered by the hands of Sayeed and Zeeahd, brothers transformed by the Spellpague and on on a mission from Mephistopheles to find the son of Erevis Cale. They encounter Gerak, a hunter and former soldier, trying to help his wife who was infected by Zeeahd by a diabolical sludge. It is also revealed that the brothers were seeking The Oracle. With that, Gerak, Orsin, and Vasen headed back to the abbey as quickly as they could.

The trio find the valley alight by several spined devils that accompanied Sayeed and Zeeahd. Fighting their way through the Devils and Sayeed, Vasen made his way to one of the towers in which Zeeahd was confronting The Oracle. The Oracle, revealed Vasen was the son of Erevis and then sacrificed himself just before Vasen reached the Zeeahd and his devils. Gerak and Orsin rejoined Vasen and escaped as Zeeahd changed into a Bone Devil.

With the protection of the abbey gone, Brennus Thanthul, prince of the Shadovar found Vasen and quickly dispatched his forces. With the devils on their heels and now the Shadovar, Gerak, Orsin, and Vasen made their way to a pond Orsin had previously identified as having some connection to his past life and Mask. The pond was now a portal and they all entered just before Brennus tried to stop them.

The three found themselves in a part of The Shadowfell that Drasek Riven, with his sliver Mask's divinity, connected with Cania, the realm ruled by Mephistopheles and the frozen prison of Erevis Cale. Riven provided a distraction for Mephistopheles and part of his forces while Gerak, Orsin, and Vasen found and released Erevis.

With Erevis now rescued they all teleported Ordulin to stop Rivalen Tanthul, who also had a sliver of Mask's divinity and sought to bring about Shar's will to destroy all of Toril. Rivalen had forced Sayeed into being the vessel from which the words to complete Shar's plan would be read. Rivalen teleported himself and Mephistopheles to Ordulin as well, bringing all the slivers of Mask to one place. Rivalen then forced Vasen to read the words on Sayeed's body, finishing the elements to finalize Shar's plan. Remembering the words of The Oracle and his dreams, Vasen stopped Shar's Eye from pulling the divinity out of Riven and Mephistopheles. Erevis was able to cut the divinity from Riven, Mephistopheles, and Rivalen. Erevis felt it was his responsibility to take on the godhood, but Riven stopped him and convinced him it would be better if he took it.

During the conflict, Erevis and Rivalen's friend Magadon Kest had been piloting the floating Shadovar city of Sakkors towards Ordulin. With the Mythallar powering the city dying, Magadon left it on its course and fled the city. With Sakkors bearing down on Ordulin; Vasen, Erevis, Gerak, and Orsin left Rivalen, grappled by his revenge seeking brother, Brennus, to be crushed by the city.
