Still REALLY under construction, this all being typed from a smartphone.
Grew up in a "respectably poor" neighborhood just outside Last Resort, with a family tradition of work in the "hero support" industries (I.E., bartending, shopkeeping, etc.)
Raised by his mother alone from the age of one, (he IS the merchant's son, pretty much) since his father left town after accusations about theft of a golden brick from a local hero were proven true. Not particularly fond of heroes growing up, but bore them no ill will either. His mother took over operation of the family store, and Gary learned to work quietly sweeping the streets of Last Resort proper clean of litter.
Was not at all expecting to be the Chosen of any god, let alone a novice one.
GTG, more details to come. United with his god in unconventional fashion, the two began their travels while searching for loved ones: the hero looking for his missing father, and the god just hoping to go home again one day.
Currently they have a tentative understanding of each other... or they believe so.
The Pride Which Goeth Before the Fall
(...or "Put Your Money Where Your Mouth Is!")
One fateful day in Godville... freshly ascended to godhood, Jimbob64 was out with some other gods his age, celebrating their ascension with a few tall, frosty glasses of ambrosia in the heavenly pub. Nothing of any real interest to the reader happened until near the end of the evening's celebrations, when a dispute broke out between the young Jimbob64 and the most senior of the elder gods present chaperoning the group. Jimbob, who evidently had one drink too many, went and shot his mouth off at just the wrong person, and what happened next would change his life forever.
What the impetuous and very drunk young god proclaimed, loudly and at length to anyone who would listen, was that the elder gods weren't really as great as they claimed to be, since they were in fact gods and must therefore be able to do anything they wanted with utmost ease.
Ignoring the warnings (and physical restraint) of his peers, Jimbob64 marched right up to the most senior god present, failing to notice the lightning bolt shining from within a fold of the oldster's robes. Rashly, he proclaimed "I can do anything you can do, old man- we're both gods! In fact, name one thing you've done and I'll top it, just to prove my powers and my point!"
The older god paused a moment for effect before responding with "Something I did? How does 'fathered the legendary hero Heracles, and made him my champion' sound to you, kid?" Jimbob64, not taking the hint/warning for what it was, continued to press his luck, insisting that Heracles was no big deal because the guy was part god to begin with. "In fact," he retorted "to prove how easy it is to make a hero like that, I dare you to choose any human in the world. Not only will I make him my champion, but he will be far, far better than yours!"
The old man, (who everybody on the planet except Jimbob64 has by now identified as Zeus, king of the Greek gods) muttered "You're digging your own grave with those words, boy. Go ahead, keep shoveling, I won't stop you."
At a more audible level, however, the great Zeus surprised everyone present by accepting the youth's challenge to pick out a mortal as Jimbob's Chosen One. He had only one condition: that his challenger swear an unbreakable oath on the river Styx that he would accept whomever Zeus offered him as his champion, and not return to the godly realm until his assigned human managed to prove his status as epic hero by completing a temple for Jimbob64 that rivaled even Zeus's own.
Anyone less drunk would've apologized and backed down long ago, but of course there wouldn't be a story here if Jimbob64 hadn't, in a fit of galactic-scale stupidity, proved himself a perfect match for his future hero by accepting Zeus's conditions on the spot, and swearing his unbreakable oath to see the challenge through.
"There," Zeus thought to himself as he watched the foolish young god take his leave to find the oddly-named hero Zeus had assigned him. "That ought to keep the little punk busy for a while. At least I'll never see him again."
It'll go here when it's made, and after it's had a while as the actual chronicle in the hero page. It's empty now for a reason.
