Jeston was born into a wealthy family from the Columbia Federation, with two older brothers who had made substantial achievements in the business and political worlds. Unlike them, he had only ever truly excelled at play. Although he had also wanted to make a mark for himself, regrettably, at least within the areas he had ventured into so far, there wasn't one that suited him.
Later on, he grew accustomed to his own mediocrity, investing the start-up capital provided by his family in some industries, and escaped the elite dwellings that made him uncomfortable.
However, no matter how you look at it, as someone who had lived among the upper-class society for many years, he was privy to many secrets unknown to the ordinary person, like ghosts, Divine Hiders, and Magic Items.
