[Dark Souls Series] How were the kingdoms when the between each cycle of the fire fading?

Were they full of humans? 

Were there any undeads? 

Maybe an occasional demon?

Were things "normal" during this period, or things are usually fucked up most of the time?

The Age of Fire was a golden age of prosperity and marvels. Or at least that's what the giants' records say. All the majestic castles and cities they left behind suggest they weren't lying. The giants killed anything that posed a military threat to them, especially dragons. Humans were there, and it appears some of them held military positions, but they didn't prosper *per se*. There's also the whole weirdness of Oolacile, which is populated by human-sized humanoids who are explicitly not human. This all started collapsing as Gwyn got more and more obsessed with the end of the Age of Fire.

Judging from places like the Undead Asylum and lore references to kingdoms and religions quarantining the undead, it seems that undead showed up late in history but before kingdoms started collapsing.

Demons didn't show up until near the end of the first Age of Fire, when the Witches of Izalith tried to make a false flame and instead created Chaos.
