"Golden Ages": the long-ago days when everything was somehow bigger and better. When great empires controlled exotic lands, and magicians ruled the elements. When the world was largely unknown, and there were new lands to explore - or conquer. When they wrote the classics, and treasures could be found in cheap pulp magazines.
"Golden Ages": not-so-long-ago, when the quest for a malleable yellow metal brought thousands from all over the world to what had been until recently a quiet Mexican backwater town, changing it and the landscape for ever. When the contacts between cultures bring conflict and change.
"Golden Ages": 12. When one straddles the divide between childhood and adulthood, not quite one nor the other, looking towards the future with great expectations.
