Three eyes... just like their name, they were three.
The basic and passive red eyes allowed him to see things far away from him, and his blue eyes allowed him to apprise things even if they were far away. He could use his third eye, the special mind's eye, when using these blue eyes. And his third silver eyes, the most powerful, and something that his master warned him to not use against any other weaker human.
But the undead army before them was a different thing altogether.
He activated his eye's third special power and his eyes, along with the white part of his eyes, glowed with a silver color, and his hair also started glowing with a glimmer of gold.
He looked like a different being altogether with those two special features, but as soon as his eyes turned to this strange silver, the pressure of the whole place inside this room's space became unbearable...
-Oooooooooooooong!
