Okay, I've had some time to digest this... and read a bit in this thread.
This is how the Eternian timeline makes sense for me. Now granted I'm not the brightest beam in the block, so please bear with me and feel free to note something if what I type here is inconsistent, I'll take no offense to being corrected.

But hopefully this may help some of us see where this story takes place in time.
Also know that just because I've done some covers... I have no idea where Val and Emiliano and Lori are taking this story. I'm enjoying the ride like the rest of you with no inside information. If any of you three could look at this post and tell me if I'm hot or cold... please do!
Here's how my mind has wrapped around the history of Eternia in this new continuity MYP and MVC told:
King Grayskull's age:
- Snakemen and Grayskull's forces battling
- Horde defeats Snakemen.
- Hordak performs the Separation spell
- Horde attempts to overtake Grayskull, and fails, result is Hordak and the Horde are banished to the dimension of Dispondos.
- King Grayskull dies in final battle with the Horde, empowers the Elders with the Power of Grayskull.
- With the Horde gone, remaining snakemen rebuild at Snake Mountain over many many years. Generations even?
- Elders build the Hall of Wisdom and rule from there?
He-Ro's age:
- Coucil of Wisdom (issue #5) consists of the "heros" of this age, including:
He-Ro, Eldor, Big guy in clothing bearing emblems that She-Ra also bears, Blue lady, turtle guy, etc... check out the comic right?

- He-Ro and "She-Ra like guy" = decendants of Grayskull? Continuing line to future kings like Miro and Randor? *ouch, except that whole not taking spouses or procreating! doh!* Hmmmmmmmm. Needless to say time goes on.
- Evil Lyn is born, Faceless one banished, Evil Lyn taken by a Sorcerer that could be Keldor... but not necessarily. The ram staff is given to Evil Lyn's new care taker.
- He-Ro ultimately banishes Snakemen. (as seen in Vol.1 #2)
King Miro's age to King Randor's age:
- King Miro battles Marzo
- Capitain Randor fights Keldor and his forces, including a very mature and powerful Evil Lyn.
- Keldor and his forces banished to Dark Hemisphere.
- Keldor dies... Skeletor is born, created by Hordak.
- The Great Unrest
- Sorceress leaves Grayskull temporarily, falls in love with wounded soldier, she bears his child - Teela is born and given to Man-At-Arms to be raised by him.
- Adam recieves Grayskull's sword and becomes the prophesied hero...
... He-Man!
So you can see with this issue, things are foggy, but they can work in a timeline... well, this timeline that I've come up with anyway.
I'm expecting this post to be torn apart by those of you who are much more versed in the history of Eternia... a facinating subject that I find myself somewhat novice.
Sorry 'bout the long post. As if there wasn't enough of that in this thread.
