Once upon a time, in the seconds before the universe saw light, there lived a pale, miserable thing.
The great burning in which galaxies were born confused it greatly, and even though it could analyse every electron of the atoms that surrounded it and rip them apart at its leisure, something evaded it.
So for a long time, it roamed the universe, searching for something it felt was missing.
One day, it came upon a small world of green and blue, orbiting a small yellow sun.
Upon this world were those that would one day be called the Estil.
It watched them for a long time, seeing what they had and had not.
Then, it came to a decision.
Once upon a time, a baby girl was born in a village at the foot of a mountain. She grew up as any child would, and seemed to know everything but understand nothing. She had seen something in the Estil that seemed to match the hole in her heart, but discovered she could never grasp it.
And the more she searched, the more alone and scared she felt.
It would be far better for her to return to the empty stars she had once roamed, than to stay here endlessly in pain.
But when she had fallen from the heavens, her power had been changed in many ways, and to return to what she once was would be a lengthy process, once that would see the Earth turned into dust.
She didn't particularly care.
Once upon a time, a great disaster came upon the land. Monsters devoured entire villages, great cracks rendered the earth, and it seemed like there was nothing anyone could do.
A young scholar in a city by the sea thought differently. He gathered every scrap of knowledge and strength he had, and went searching for this world's destroyer, to find it and end it.
When the end came, the girl had neither a smile nor a tear on her face.
The calamities had ended, but the scholar and his friends saw worrying portents in the stars.
One day, the Destroyer, the Suneater, would live again.
The Scholar, one leg lost during his adventures, sought to sacrifice himself one last time, stabbing himself through the heart in a great ritual.
The Anathema would be reborn one day, in all of its awesome power, but so would he, to stop it over and over again.
Once upon a time, the sun rose, and fell over the horizon, and fell again.
Again and again and again.
They would be reborn, their past memories a grinning ghost in the mirror, they would remember, they would fight and they would die.
Over and over, as the Estil rose and fell, as the Earth changed and changed again, as a new species came to dominate the small blue and green marble.
He had never seen her cry or smile, not even when he stabbed her through the heart.
Nothing in this world seemed to matter to her.
Once upon, there was one who sought to save the world, to give it a brilliant bright future.
After long enough, he realised such things didn't matter to him anymore.
He was tired.
Once upon a time, there was one who decided to change things this time round.
He would not hunt down the Anathema, not this time: he would serve her and her wishes.
Perhaps, as the Earth returned to stardust, he would see her smile.
My take on a possible version of the Titan: since he has the Knightly aesthetic by processes of elimination, I decided to follow a "Lady and Knight" theme.
