Fourth Age Past Lives

[Nox]

I have a question. I know some of you have some 4th age past lives. I was wondering what criteria they fall under.  Other than the dark one isn't there.  It's thriving after Rand saves things, tech and magic are starting to make a resurrgance. 

I'm just curious.

I'm considering adding another life to Nox's past lives.  One in the 4th age that is a spun out Hero of the Horn.  (Though I don't know if it's necessary as Geb might possibly qualify as a hero for the actual things he did before the god wars.)  Which I don't actually know if he participated on what side lol.
