Eternity

He first met her during the height of the Roman Empire. He was a high ranking roman and she, a mere slave in his household. He had a wife then and children too but that was merely a formality, a way for him to get ahead. She was what he looked forward too in both his sleeping and waking moments. All these were things she couldn't possible know being just a slave.
He wanted her but he also wanted her to come to him of her own accord. He loved her and wanted merely a reciprocation of this love. He wooed her as boldly as he might and soon she overcame her suspicions and submitted to his adorations. But this was to be only the beginning of the tragic love story that would span centuries and lifetimes.
When he was alive, he gave her 2 greatest gifts a man could give. His undying love and her freedom. She gave him all she had to give, her whole self and a promise to love him for all eternity.
A promise made by one so pure as she, could only be taken as a vow before the gods and they held her to it mercilessly.
When he died, she was devastated and stayed nightly by his grave refusing to leave him except by the light of day for that was when his family would come to make sure his name was not sullied by her pressence. So she came only in the shadows of the night, a secret forever, a shadow until the day she too passed away.

The second time he met her was on market day in the dark ages. He was a mere peasant and she, gentry. Oh what a reversal of fortunes and yet still his love forher burned strong. She, as if remembering the promise made a lifetime ago, noticed him immediately and set her heart upon being with him. She forsook everything only to have him betray her for even though her soul remembered her vow, his soul had long forgotten his. So in the end, even love was not enough for as soon as his hunger for her had been satisfied, his desire for survival took over and he fled for fear of death and left her ruined and disgraced fit only to be killed. She died loving him, forgiving and understanding.

The next time they met, he was the Witch hunter General and she the accused. He loved her and coverted her and there was nothing to stop him from taking what he wanted and then silencing her after if only she didn't love him back with such ardour. The purity of her spirit and the intensity of her love captured and imprisoned him and they made they escape in the dead of the night. It was 5 years before they were discovered, a man and wife with a babe in arms captured and brought to trial. She was evermore the witch then for having bewitched him and using his essence to create a perfect human body for the spawn of the devil. They condemmed her to burn but not before they wrenched the babe from her arms and drowned him before her very eyes to kill her spirit. The day she hung, he swung too but in his own dark cell away from the crowd.

Now their paths have crossed once again and once again they've met, collided and loved. But perhaps with the trials so vividly present in his mind he cannot let himself go for fear that he will lose her again. But she, she cannot help but love him for her vow was one made to last for all eternity and no matter what form she has taken or which century it is, she will always find him and love him regardless of whether he would be able to love her back. Hers was not an easy vow to make but she made it anyway without knowing but accepting nonetheless. How many lifetimes have passed and how much suffering she has endured for him and still she goes on loving him until the very end when there is no life to come back to and no century to live.
