Fourth Age Past Lives

[Thalia]

I don't think there are many explicitly detailed 4th Age lives, and those we have mostly occur either at the beginning or end of the Age. The 3rd Age rp will head into early 4th Age once it gets post the Last Battle. And late 4th Age heading into 5th Age includes fairytale rebirths if there's anything there for inspiration. By the end of the Age at least one society evolves into the Semitic pantheon, in which channelers were revered but tightly controlled. Other than that there's not a lot of detail. And obviously an Age lasts a very long time, so you could just make something up however you like and fit it in the middle. It's the age of Heroes after all.

The Ages page just says this:The Dark One’s touch on the universe is gone from this age. Men and women who channel the One Power have come together to rebuild the world following the Last Battle, the epic war of their time. Due to feats rediscovered by working the two halves of the Power together, everyday way of life advances. Tales of the Dragon, the savior of the 3rd Age, flourish, and remnants of the Seanchan empire transform into a society where channelers, while revered, serve the common people. Order and control begin to dominate by the end of this Age, and another catastrophic war is barely averted.
