What is the full chronology of the ages in the Dark Crystal franchise, and how do all the different works fit in them?

Question

From perusing the Dark Crystal fandom wiki I think all the 'dietetic' ages are:

1. Age of Innocence
2. Age of Harmony
3. Age of Division
4. Age of Power

With the Original movie and Age of Resistance taking place in the Age of Division, and The Power of the Dark Crystal taking place in the Age of Power.

But it seems like there's a lot of other media out there set before, after or during those stories.

Are these all the ages, and if so what works of fiction take place in each?

Answer 1

This page seems to answer that question, grouping the various comics etc by Age (and even in subdivisions inside an Age where appropriate).

If you look at its notes, its reading order includes even more books (e.g. novelization of the movie etc.).
