This is very important to understand the rest of the story.
Since Thanatos has faded there will be no Doors of Death that need closing or Gwen being revived.
No demigods going to Alaska but we will assume that Frank as Hazel have just as much importance.
This is basically just a regular war, well as regular as a war including Gods and Monsters can be.
Thank you for reading this, if you didn't then good luck understanding the rest of the story.
So yeah,
Bye-ah!
