once upon a time, a legend was whispered among shadows. it was a legend of hope. it was a legend of dreams. it was a legend of light. it was a legend of dark. this is the legend of delta rune for millenia, light and dark have lived in balance, bringing peace to the world. but if this harmony were to shatter... a terrible calamity would occur. the sky will run black with terror and the land will crack with fear. then, her heart pounding... the earth will draw her final breath. only then, shining with hope... three heroes appear at worlds'edge. a human, a monster, and a prince from the dark. only they can seal the fountains and banish the angel's heaven. only then will balance be restored, and the world saved from destruction.
