Sentinels

The Sentinels are an ancient order of warriors dedicated to the protection and advancement of mankind. They are the primary protagonists of the fanfic series, The Hunter

History
The Sentinels were founded alongside Illuminati by Seth, the First Sacred Gear wielder and third son of Adam and Eve sometime after the Great Flood. Having lost faith in God and now focused on protecting humanity, Seth gathered powerful individuals, both in influence and strength, including a large number of Sacred Gear wielders. Many hisitorical figures were also members too. Under Seth's guidance, the Sentinels acted as the shield and sword of mankind against the supernatural, while the Illuminati helped guide humans into advancement and enlightenment. After the Great War, the Sentinels began accepting human-hybrids such as demigods, nephilims and cambions.

Trivia
The Sentinel's symbol is the Trinity Symbol, also known as the Triquetra. It represents Seth, who is Adam and Eve's third son.
