The colony is a place of special spiritual significance.  Some humans are taken there, and others find their way to it.  People are also born there.  The colony provides a way to escape from the evils of the human world. Raguel Tuemini appears to be like other young people in their twenties.  Humans can't tell that he is a spiritual being.  He is considered quite unusual in the spiritual world.  His mother is a Nephilim, and his father was an angel.  He has Nephilim energy, angel energy, and a human soul.
Raguel's work is protecting humans from demons. After an intense battle with a demon, Raguel finds himself at the colony.  When his mother's soul is taken to hell, he embarks on a personal mission to recover it.  What he discovers during this time challenges his perception about everything in his life that he believes to be true. It is a journey that forever changes Raguel's views of the spiritual world, the human world, and himself.
