White Magician Pikeru and Ebon Magician Curran
Long ago, Fire Princess ruled a kingdom that is now lost in antiquity. She was a feared sorceress who practiced the magic of Fire, and using it, she could drain the power from her enemies while strengthening that of her allies at the same time.
Darkfire Soldier was her beloved royal consort, a powerful warrior of Fire. His skills in magic were small, but he would protect her at all costs.
One day, Fire Princess came to her husband with joyous news - their love had been fruitful, and a child would soon come to them. Darkfire Soldier was nervous... The thought of a son or daughter scared him, because he knew of the dangerous Trial that his wife had undergone to gain her crown. He resolved that he would find a way to help his offspring... But how?
Doing research, he found a reference to a temple located in a strange place where, supposedly, a great power of the element of Fire existed. He went alone to find the place... And nothing was seen of him for a month...
When he returned, he was in terrible shape. Scars covered him, and even worse, his flesh seemed to be running like molten wax! Fire Princess was horrified. Her husband told her he didn't have much time left, and told her to listen carefully... He placed three scepters before her.
His research had lied. No powers of Fire existed in that terrible temple; it was a den of Chaos, a raw combination of Light and Darkness. He had foolishly entered its inner sanctum, and it had horribly cursed him. But he managed to escape with his life, and with the three scepters.
One bore the power of Light. The other bore the power of Darkness. The other was a magical artifact of Chaos, which could be used by forces of Light and Darkness combined.
He told his wife that when the child was born, to teach him or her one of the three forces, and when it came time for the Trial, the corresponding scepter would help. Then he gasped, and ran off.
She told her servants to follow, but they came back to report it was too late. The curse had eventually run its course, transforming him into a mindless abomination that lashed out at everything in its path. People who encountered him and lived started to call him - or it, as they might as well now - the Lava Golem, a cursed engine of destruction.
Long after giving birth, Fire Princess sought out the thing that her husband had become to try to end his misery. But it was no use - its draining power was now even greater than hers. All she could do for him now was mourn.
But when she did give birth, she got a surprise - twins. Two twin girls, whom she named Pikeru and Curran. She couldn't neglect either of them or show a favorite, but fortunately, her husband had brought enough to share."
Thus, when the twins got older, she had Pikeru tutored in magic of Light, the power of healing - the part of Fire Princess's ability to heal her allies. Curran was taught the magic of Darkness, which reflected her mother's ability to sap the life of her foes while doing so.
But Fire Princess remembered her husband's horrible fate, so she gave strict orders to their tutors that neither Pikeru nor Curran were ever to learn Chaos magic. Such skills were too dangerous.
But that left one problem. Since no Darkness existed in Pikeru and no Light existed in Curran, the sisters repelled each other and couldn't mix. Neither ever had kind words for each other, and got into fights and quarrels often. Soon, their mother believed she was the only thing keeping them from actually engaging in combat.
Once it happened. No one knew who struck first, but at one point the two sisters' quarrel turned into a duel of spells and fists. They soon found that they were equally matched, and the fight ended with both of them collapsing from exhaustion. Their mother found them, and once they gained their strength back, she ordered them thoroughly spanked to discipline them. The soreness in their behinds prevented another outright fight, but they still would despise each other for the longest time.
Finally, the same oracle that gave the Trial to Fire Princess told her that the time had come. But when she discovered what awaited them, she thought that the two scepters of Light and Darkness may not be enough. The ogre that her daughters would be charged with defeating was incredibly powerful...
Fearful that her daughters might perish, she gave Pikeru the one that represented Light, gave Curran the one that represented Darkness...
...and then entrusted to both of them the one that represented Chaos. She told them that in a time of crisis, they could combine their powers for even greater power.
Casting hateful looks at each other, they went...
And true to their mother's fears, the Trial proved incredible daunting. Having no options remaining, they had to cooperate. Again, the one who suggested it is not known, but the other agreed.
They cast the spell of Chaos, and they won.
We can onlyimagine what kind of life Princess Pikeru and Princess Curran had after that.
