Long ago the demons were unleashed on the world of humans and since that day nothing has remained the same anymore. The bloodthirsty devils move here and there at night and just suck the blood of every living soul that comes in their way.
Humans now face the threat of extinction as they think soon everything would be over for them from all sides. At this time author, Peter V. Brett provides the world of humans with two heroes. Arlen Bales is one of them and has tattoos on his body that protect him from the attacks of the demons.
The other one is Jardir who has weapons that can extinguish any demon within seconds. Together the two start a campaign against the Swarm that has approached the land. Renna the wife of Arlen is also part of the team and these three start their mission towards the core to stop the Swarm.
Pete Bradbury during narration provides these heroes sad tone on different occasions to depict their inner feelings. They know that their chances of returning from the mission are something below zero but for the sake of the human race, they start the mission.

The two friends have everything in stock which is needed for the fight but their friendship gets threatened which weakens their bond. The enemy tries to make them weak through conspiracy but from the inside, they know what they have to do to put an end to all this madness.
