Event #5- Nico looks for the Doors of Death in the underworld
Seven half-bloods shall answer the call,
To storm or fire, the world must fall,
An oath to keep with a final breath,
And foes bear arms to the Doors of Death
The Doors of Death in this situation, in a simplified manner, are the doors that keep the spirits of the dead from returning to the world. So, in other words, people who are killed or die, don't die. They die, and then more or less "wake up" a few seconds to minute later. So discovering and closing these Doors are important.
Below is a picture of the Doors of Death, the point where spirits are supposed to be locked in to the underworld.
