"The way of the sentinel is to protect those who need to protect, and strike those who dare hurt the protected. To stand your ground no matter the task, and fight to the death for as long as it lasts."

During the years a very powerful group was created, one to protect the ones that need protecting. The Sentinels. A group of highly trained and very powerful soldiers. But over the course of history the group fell, taking the others with them. All but four survived. And have remained hidden for years. But when One of the four goes rouge and appears as a threat of safety to the world the sentinels must come out of the shadows and fight the new evil.
