Technology wasn't the way of life in the old times, it's a new phenomenon that has emerged by the ingenuity of man.
I would say something more like.
"Over the eons, the ways of the past have been forgotten.
In time, new tools have developed, such as Steel,
Gunpowder, and Steam Engines based on the intellect of man
rather than the power of the soul, and peace reigns once again."
EDIT: I see you already used eons in your first page, perhaps
"As the tides of time eb and flow, the ways of the past have been forgotten." or to be shorter "as time ebs and flows, the truth of the past has fallen into obscurity and myth"
you could also replace my last line with "... and tranquility returns to mankind"
It might also be useful to establish that magic was prevalent, common, and the power of the day in the past before declaring that it vanished.
you could also end with something like
"Could the ambition of man drive it extinction once and for all?"
Most of what I've written is too long, but feel free to use and condense it for your own evil purposes if you find any of it worth a damn
