What is the main conflict in The Sandman: The Kindly Ones by Neil Gaiman?

THE KINDLY ONES follows Lord Morpheus, the master of dreaming, in his conflict with the Furies, who externalize his internal conflict over having killed his own son. Morpheus has told Lyta Hall that he will some day come for her son Daniel, and when Daniel disappears and she believes him dead, Lyta goes on a quest in the dream world to find her revenge. Daniel, however, is in the Dreaming, rescued by Morpheus's minions. Lyta no longer wants revenge, but the Furies are already set in motion. Morpheus, facing his own guilt, chooses to go with his sister Death, leaving young Daniel the heir to the Dreaming.
