The song may be over, but the story never ends. ;]
With each step forward, Amy felt as though she was floating further and further away, no longer herself anymore. She was a different presence- a foreign, alien one, not a personality but just a being. It ached, causing her mortal body more pain than she could bear. Nevertheless, she continued to stagger forward, each foot the arm of a clock, ticking its way to the final hour.
The sun continued to climb in the distance, but it was little match to the golden dome and the star within it. But as she moved forward, Dark Mist finally found the strength to retaliate-
Straight into her side.
Amy screamed, though no sound came out. Unfocused by the blazing heat, Dark Mist had veered from course, resulting in a misguided hit. While one bladed arm missed completely, the other tore at her right side, tearing away flesh just above the hip. As the skin and gore disconnected with her body, it burned and vanished into nothingness leaving a horrid burning scent. But something greater occurred.
Where a reasonable chunk had been scratched away, no blood dripped. Rather, a plasma-like fluid filled the empty space, golden and painful to look at. It flowed eerily through her body, like lava, burning inside-out. Underneath the flesh, there seemed no organs, no bones... only light.
She didn't need to glance down to feel it, but she couldn't resist. Raising a glowing hand, she poked the plasma. It quivered like water, but continued to flow, running her body at a burning pace. The wound didn't hurt physically, but in her mind, Amy felt as though a piece of herself had been eroded away, revealing something much more divine, more foreign. Less real.
Augh... God... What is... I...
Amy looked forward, unaware whether she was breathing anymore or not. But she noticed she was still walking, only feet from Dark Mist. She didn't stop until he was within an arm's reach, his blackened body boiling with the stench of fear and nightmares and death.
Slowly, she raised a hand, and placed it on its forehead.
"...Good morning."
From her wound, the plasma began to seep outward, spilling and overflowing. Rather than falling to the ground, it ran over her skin, covering her completely. Some distant glance in her golden eyes read of fear, but otherwise, Amy seemed calm and no longer herself. In moments her body was a humanoid of golden burning plasma, constantly swilling, always churning. Forever burning. As the plasma spread, it finally reached her hand, connected to Dark Mist.
"...For now..."
And so, within the golden dome, the golden star exploded.
