Children of Gabriel

The Children of Gabriel is a mysterious, cult-like militant group in conflict with the Sanctum Citizens. They are interested in killing the Primes.

History
The Children of Gabriel was founded sometime after the Mission Team Alpha landed on Sanctum. They became a cult-like rebel militia group. They are possibly connected to Gabriel Santiago.

In "The Children of Gabriel", they successfully raided the Gagarin and stole guns from the ship. They beheaded the corpses of the three Primes, Viktor, Faye, and Daniel, that were killed on Eligius IV and took the heads with them. They successfully infiltrated the Sanctum settlement and attempted to kidnap two Hosts, Deliah and Rose. Clarke Griffin with Sanctum guards were able to successfully recover Deliah, but another abductor got away with Rose. Outside the perimeter, they successfully captured Octavia Blake after she tried to attack them.

Society
The Children of Gabriel is a cult-like militia group. They serve a mysterious figure known as the Old Man – it is unclear if this is someone alive or a deceased ancestor (similar to how the Sanctum Citizens worship the original Primes). It is possible the Old Man is Gabriel Santiago and/or the person referred to as the demon Gabriel by the Sanctum Citizens.

Their goal seems to be to kill all the Primes. After beheading corpses of three Primes, the group chants "Death to Primes!", over and over. They also want to kidnap, and possibly kill, any Hosts, that is, those having the Royal Blood and thus potential to be future Primes. In order to do this, they patrol the radiation shield and look for opportunities to get inside and to watch out for any Primes walking out. The Sanctum Citizens are aware of them and use the radiation shield to keep them and other dangers out.

The Children of Gabriel know a lot about Sanctum plants. They use the forest as their weapon, like Xavier did by spraying Octavia with spores.

Notes and Trivia

 * The group has some similarities with Grounders. They hide in the woods, wear camouflage clothes, and are in conflict with a more technologically advanced society.
