Lunaculi

The Lunaoculis are a group of people native to one of each of the seven great continents of Patria. They are the seven who, through existence alone, maintain balance between good and evil. They are easily identifiable by their unique heterochromatic eyes (crimson in the right and blue in the left) like the twin moons of Patria. There always seven, no more no less, continuously reincarnated when one dies.

The Legend of the Lunaoculis
"In ancient times, a great evil crept forth from the depths of the Underworld seeking to enslave all of Patria. Many years of struggle between good and evil ensued with evil nearing victory. Then, seven young warriors, one from each continent ravaged by the great evil, appeared as if out of nowhere. Together they battled the evil lord for the fate of Patria. Their strength, unbelievable. Their power, unstoppable. The evil was defeated, and the seven warriors returned home, and their names were given to the great lands they saved. Since then, the seven warriors have been reincarnated and have since maintained the balance between good and evil, always awaiting the call to gather again, should that balance ever shift." - An ancient text describing the legend

Abilities
Despite their role as balance keepers, the Lunaoculis exist one a single principle, "Alone we're weak, together we're strong." Meaning that alone they are only as powerful with their own strength, but the more that are nearby the more powerful each becomes. And when all seven are together, they are unbeatable.

Reincarnation
Since the first seven, the Lunaoculis have been continuously been reincarnated so that there are always seven at a time. When one dies, a new one is born at least a few weeks after it's predecessors death. It should also be noted that the reincarnations are not race specific, meaning that any race, by chance alone, half-breed or not, an produce a Lunaoculi.
