The Great Kings

''The Great Kings: Shuichi and Shuji Tsuneo. Two Brothers from a town in the centre of Arcerra. Creators of the Artifacts, the only two to have killed a Region Tyrant, and the ones who made the Region which resides in the centre of the Continent into what it is today, which was named after them in their honor.''

They had some nex level of LEC; their entire bloodstream was made from Life Essence.

All of their eyes, not just the iris, was the color of Life Essence. It Glowed more/less brightly depending on how much Magic they had left to expend.

It changed color to that of the Element that they last used (Just used fire = red eyes. just used water = blue eyes), and will slowly go back to the green

The Great Kings had total control over the three things all people with LEC can control. Absolute.

Also, since they were practically made out of Life Essence, they were immune to Flow Deprivation, Flow Overload, and any risk of dying whilst programming Life Essence

if ethraksha can absorb flow. that will lead to the great kings taking tiny amount of ethraksha and using the air around them to have a near unlimited reserve of the stuff.

orrr i could make it so that the great kings do this so much that they thin the air of arcerra of its aura, leading to a bunch of health problems in Era III humans.

That's actually quite good.
