As Rey and Ray looked at Arad's chest, their eyes opened wide as the radiant light flashed. It took them a fraction of a second to move, but that was enough for Arad to blow up, drowning the world in fire and radiation.
As the world was painted red, the continent trembled, and the sky cracked. A mushroom cloud of crimson flame touched the heavens as a devastating shockwave shaved the mountains flat.
Arad had transformed into his draconic form and blasted the whole area to get some distance away from the twins. Just in case they used their power in a way he didn't expect.
Something ghostly flashed through the ash and smoke, two of them. Unseen to normal eyes, but Arad could barely perceive them. Invisible, translucent massive drakainas with each of them at least a thousand kilometers long, not counting their gargantuan tails.
