No they do not. Elias is now the Soul Catcher and fully bonds with Mauth forgetting his feelings for Laia and his name. The Nightbringer gets all the pieces of The Star and releases the Jinn to retake the world, he also kills every augur except Cain for revenge. Laia and Helene are in Delphium with Livia, Zacharias who is Marcus's son, Avitas Harper, Dex and Faris (I think). Laia askes Helen if she could train with Serric Steel and Helene agrees. The barbarians have taken over Antium and Keris becomes empresses of The Empire and Zacarius is the biggest threat to her and is to be killed. So no not a good ending for the characters.
P.S. It's been awhile since i read the book so if i get a few things wrong im sorry
