The Hunters were vicious types of creatures that lived in Northern continent crossing over half of the Tri-Star Continent, whilst half of it belonged to the Runners.

The Tri-Star Continent used to belong to the Runners, but they went to chaos when the Fire Nation attacked... um.. WHEN the Hunters attacked!

The Runners were all powerless against the Hunters, but the Heavens did not forsake them.

When all hope seemed lost, a very powerful entity appeared amidst all the chaos, he protected all the Runners from all the Hunters and fended off all of them.

They called him, "The Sentinel" he was the one who kept watch after everything was almost over, it was the so called "heroic move."

No matter what, as long as he was able to save the Runners from their impending doom...
