Damien Whitechapel did not grow up knowing his family. To his knowledge, his parents were poor and his siblings sickly. The most he can remember about them was waking up one day and not having them. So he turned to petty crime to feed himself and his siblings. It didn’t last long, as his siblings were soon to follow in their parents’ footsteps and then Damien was all alone.
He continued his life of thievery in order to survive, growing particularly adept at his trade as he grew older. He became an adventurer to try and right the wrongs he had done (and maybe because it paid well). On one of his missions, he met a Goddess who sought his aid. With the aid of a silver tongue and multitudes of luck, Damien managed to woo her and help her at the same time.
When all was said and finished, the two settled in together; at least for a little bit. Being a Goddess, she had to leave. Saddened but understanding, Damien watched her go. Months later, Damien received a gift from his departed love in the form of his oldest children, Minerva and Moses; tangible proof of their love. A few years later, he would have another son, Perseus, and each and every one of them would grow up to become adventurers, much like he was.
To his surprise, the time he’d spent with the Goddess had affected him. No longer was he human, but an Eternal. His time on the planet had lengthened exponentially, but...he didn’t know what to do with that time. So, he chose to simply settle down instead.
