Chapter One - Let the Games Begin

Anger and jealousy can no more bear to lose sight of their objects than love.
-George Eliot

If anyone had been asked to describe Cain Knightlord back on the Ark, the same words would have come up time and again. A pacifist, gentle, everyone's friend, the peak of genetic achievement.

He had been the yang to Abel's yin, he had been the opposite tug to a violent soul, the one who maintained violence was wrong and they were all human really.

What future do you want, Abel?

A question that had been asked time and time again, with his hand pressed to smooth glass while his brother sat in solitary confinement for solving yet another problem with his fists.

The golden haired benevolent leader of the Mars colony, capable of nothing but love for those around him. However, the thing about love... it's dangerous, perhaps far more dangerous than any other emotion, and it gives rise the most easily to other more ugly side-emotions. Jealousy, envy, obsession, possessiveness, and then hatred.

Cain loved Abel. Deeply and completely.

Perhaps it had begun as an innocent love, but it had warped beneath the surface on so many levels, sprouting other less pleasant thoughts to hide under the veneer of the angelic pacifist.

Jealousy... of Lilith and Abel, the reason switching and changing depending on mood or situation. He was furiously jealous of Lilith for stealing Abel's affection and time, for daring to command his heart and soul when they were supposed to be two halves of a whole. He was jealous of Abel for having Lilith, when his twin was inferior genetics - just spare parts - and Lilith should be with him as the superior specimen.

Envy... of Abel's ability to express his true emotions on the surface so easily. His strength of conviction to stand up for those who had held them as tools and hurt them so easily as if they were less than human.

Hatred... of the humans. This was one so long fostered, for all the same reasons as his brother. He hated being used as less than human, hated being a pincushion for experiments, hated what they did to his family... a deep and frightening hatred that he kept buried.

Until the day he died.

Then into that black oblivion had come whispered voices asking him to submit, promising him the power to make everything right finally, vowing to take away the pain and servitude from his family finally. Perhaps he didn't truly understand what they were, or what would happen, but he had willingly submitted to their thrall... and when he opened his eyes again, Cain Knightlord was something more than he had been.

Evolved.

From clone to Crusnik, his vision finally clear.

What future do you want, Abel?

Perhaps he hadn't known himself back then, perhaps Abel had never known either. But now he knew. The future could be only one thing, the pain of the world cried out to him and there was only one way to deal with such a festering illness as the humans. Only one way to heal the world they had infected with their wars and suffering, their greed and selfishness.

Rebirth through cleansing fire.

It had only seemed right Abel take 02, even in this form and with his mind more than half possessed by the insanity of Crusnik, the obsession with his brother didn't fade. It simply warped to become something much, much darker. His brother, his real brother, understood the need to destroy this world to let another rise from the bloody ashes...

It had been savage perfection for decades as they waged a war upon those helpless creatures, ants before gods that would inevitably destroy them Contra Mundi and proud of it. Until she had spoiled it all, until she had come to stand between them again and tried to take his Abel from him. There was only one thing he could do to keep his brother with him, to keep them the perfect gods raining justice on a broken world.

I've removed the negative element.

Yet somehow it had been a miscalculation, heady and thrumming with the dizzying sensation of combining two sets of nanomachines in one body, he had been helpless against the unexpected rage that had overtaken Abel and driven him to be pushed from an airlock.

His marvellous brother, a god of destruction and death, had become a broken thing mourning in the tomb of a dead woman. It had taken years to regenerate from ash, and even then his body remained unstable. He had been forced to ally himself with a small organization and help it grow to something terrifying under his motto.

Let his broken brother rot for all he cared, this world would be his with none to stand in his way. Little Seth didn't count, ensconsed in the Empire she had created for herself, she wouldn't rise to the defense of the humans. It would be his, the world purged centuries after it should have been. But then one had come to draw Abel from his tomb, a new 'hope' for Abel to focus on, a new woman to fix his heart and promises on. Perhaps not in the same way, but it had been enough... and now his brethren was being forced to do the bidding of its host, bound to slavery serving that which they should destroy.

He had ignored it for a long time; after all, she was no threat to him. A mere terran woman, and a dying one at that, pathetic and infinitely breakable. But it had begun to irk him, so perhaps it was time to remedy the situation. She had nothing to offer him, no nanomachines to take and no life-sustaining bacillus, but at least she could prove amusing for a time.

It was time to show Abel once more there was no room for negative elements in his life, a life that should belong to him once more.

"Isaak." Relaxing back in the bath of sweet-smelling liquid used to sustain his body against the deterioration that plagued him, he called to the air for his butler knowing he would hear.

The butler appeared almost at once, shadows bringing him to his master's side to bow deeply on one knee, raven hair spilling around his knees like a smooth curtain. "Mein Herr."

"Don't you think a tea party would be such a wonderful idea~!" His smile was bright and deceptively goofy as he pushed damp hair back from his forehead. "It's been so long since I had a nice tea party... back when I was child, my sister had a china doll that we used to play with for pretend tea parties. A smooth porcelain thing with big eyes and blonde curls, it would be a shame to hold one without her."

He heaved a melodramatic sigh, pout coming over his lips as he blinked innocent blue eyes at his butler. "I know it won't be quite the same, but I'm sure you can find a suitable candidate to fill her place."

Isaak smiled, long and slow, he was well used to his Herr's flights of fancy and distinctly odd ways of making his requests known. But this could only mean one thing, and it would surely be his utmost pleasure to fulfill it. "Of course, Mein Herr. Will there be anything else?"

Cain tapped his chin as though thinking, long finger glistening with droplets of that odd liquid as he moved it in the dim light. "When we had those tea parties as children, Abel used to be so uncouth. He broke the doll at the last one... I'm sure he'd be more careful with the toys if we gave him a second chance, hm?"

Another bow, deep and smug, before Isaak rose to his feet and let the shadows surround him again. Vanishing to extend the invitations.

Let the games begin.
