I made a timeline of IRE history:
-Ayar creates Achaea, Achaean Elder Gods, Aldar, etc.
-Ayar also secretly creates nega-Achaea
-Yudhe exists in Lusternia. Splits into Magnora, Dynara, Nameless Son of Yudhe etc.
-Ayar split himself into Ayar and Proteus
-Dynara creats Soulless, Lusternian Elder Gods, etc.
-Magnora eats Nameless Son of Yudhe. NSoY vanishes from Lusternia.
-Magnora and Dynara go looking for NSoY.
-Unnamable Horror appears in Achaea. Rapes Maya. Humans are born.
-Unnamable Horror is banished from Achaea.
-AEG start fighting eachother like mad. Recruit many extraplanar armies.
-Armies include Bug People, Elementals, Crystal People, Demons, Cat People, Elfs riding giant spiders, Undead, Giant Regenerating Grey People, Dragons, etc.
-Entropy and Discord show up in Achaea.
-Proteus and Discord have a fight.
-Entropy and Discord get splattered across Achaea.
-Ayar and Proteus fuse into Sarapis
-Meanwhile, Lusternian Elder Gods fight Soulless Gods.
-Soulless Gods get splattered across Lusternia, then reassemble.
-Soulless Gods slaughter Lusternian Elder Gods.
-Shards form, opression by Soulless Gods.
-Achaean mortals do crazy stuff.
-???
-Aetolia splits off from Achaea somehow???
-???
-Lusternian mortals become Vernal Gods, fight Soulless Gods.
-The Almighty Kethuru is banished beyond the Astral Plane by Vernal Gods.
-Celestine Empire starts up in Lusternia
-Celestine Empire released the Almighty Kethuru.
-The Almight Kethuru gets blasted byond space and time by Project Paradox backfireing.
-The Almighty Kerrithrim shows up and attacks Aetolia
-The Almighty Kerrithrim gets vaporized.
-Servelan de Vermiis summons Nameless Horror.
-Servelan de Vermiis fuses with Nameless Horror. Eris is created.
-Eris does crazy stuff. Eventually takes some humans and flees through space and time.
-Magnora and Dynara find NSoY. All three fuse into Estarra.
-Estarra shows up in Lusternia with humans.
-???
-Avasyu, Lord of Creation creates Imperian?
-???
-Giant flood.
-Cults of Illuimnas and Shallah are founded.
-Cult of Aesir founded, city of Stavenn built.
-Petty infighting.
-Suddenly, the Moon explodes.
-Orcs attack from the east.
-Scorpion people born from human stock.
-Demonic rifts opens in the north.

With that out of the way, I think we can safely say the following:
-Magnagora, in an upcoming event, will use an extra-planar portal to try to conquer Achaea, only to get their butts whooped by dragons.
-Some Glomdoringans, Kephera, Lucidians, Orclach and Aslaran will also go to Achaea, but not try to conquer. They'll intergrate and we'll never see from them again.
-Orcs from Shallach will get ahold of an aethership, pilot it through the Void, crash land it into Imperian's moon and invade their past.
-Magnagora will use a different extra-planar portal to try to conquer Imperian and be highly successful at this untill the portal breaks.
-The Achaean Lords of Chaos are actually just a group Lusternians in a manse somewhere.
-Servelan de Vermiis is secretly Magnora/Dynara/both fused.
-Eris is Estarra.
-Dynara tried to mind-control Proteus and lost.
-The Son of Yudhe raped Maya.
-Lusternia is the Anti-Achaea.
-Aetolia is the hell dimension that exists beyond the Nine Seals.
-Vortex and Shallamar, in the past, contacted extra-planar mortals. Alternatively, Morgfyre likes messing with people.

We could beat Achaea. Magnagora just has to be willing to use weapon X. (AKA unleash Kethuru into Achaea and wait.)

Kethuru vs Zsarachnor?

Poor Kethuru, all he wants is noms.. and cuddles. Kethuru loves cuddles.

You end up with this:

Actually I thought Eris being Estarra was intended as part of Lusternia's creation myth/opening to the public advertisement.

Aetolia is supposedly some alternative universe bubble thing that was created to hold some rebellious god from Achaea, I think? Was before my time but I hear there was an event in Achaea where stuff like Hashan got destroyed or something.

I'm really confused about your timeline. Is Lusternia in the future or something? That Kerrithrim stuff only happened a few months ago.

Aetolia's external creation: Basically, there was this great big chest floating around (in Achaea) with a note saying "DON'T OPEN THE CHEST!". So people open it. Several times. Inside was Varian, who started fighting Sarapis for control of Achaea. Sarapis wasn't strong enough to beat him, so he created Aetolia (a copy of Achaea) and shoved Varian in there.

EDIT: And the timeline is missing some stuff. I mean, Kethuru's been back several times - he wasn't blasted away entirely. Plus, IIRC, Kerrithrim wasn't vaporized - just killed by having his heart chopped up and dropped to the bottom of a massive pit.

And, of course, there's the whole thing about "They may not be coordinating anything, the creations being the sole exception to give Achaeans a nice fuzzy feeling".

Yeah, I've always figured that the nameless realm/dimension that Yudhe's son entered was Achaea or else linked with IRE in some other way. I haven't read the histories of the other games too thoroughly but it makes sense at a glance. I expect some massive crossover event sometime in the future if the games stay in business long enough.

Really, it's all Cuddles wants.

Everyone should click the picture too. I think the song in the link is very appropriate.

Ia Ia Kethuru Fhtagn

While all this speculation is great... we allready know what really happened.

Lusternia exists outside of "normal" time. That, or its time runs really really fast compared to the other games.

If they all do happen to be in the same 'multiverse', there's no reason to think they all run on the same timescale. Or that their time runs concurrently and parallel, time could be mutable when crossing between.

My oldest lusternia character, Shiida, that I started at 16 years old, is 117 years old now. She's only, roughly, a 4 RL year old character. My character in Achaea is 164 and I've had her for going on 7 RL years. I think Lusternia goes faster than the rest.

Edit::

Morning ramble. Don't know what I'm talking about.

This will have stuff in it again when I figure out wtf I'm saying.

What is "Kerrithrim"? Some event I missed?

Cthulu, Aetolia style. Ate a goddess. (My patron. )

Recently I was reading the riftwar saga in preparation for MKO coming out, and I couldn't help but notice similarities between achaea's Vertani and Feist's Tsurani. Perhaps more crossover
