There’s an ancient saying in Great Ruins, ‘Don’t go outside when it’s dark.’

“The Shadowx, the name of a warrior who does not have any elemental powers.Fighting those who stand in his way, his goal is still ambiguous. But, the light will be shed on it later after.”“A world which is led by elements, an era in whom humanity took control of the elements which are 4 main elements (Flame, Frost, Shock, Terra).”“A threat known as the dark powers came to destroy this empire of elements which is held by the strongest 3 elemental warriors, The Emperors.”“Even me, I am a warrior named Radiant. Time shall come to reveal everything, EVEN...ME.”
