2,000 years ago: Humans acquire (primal) magic, and Elarion is founded. Humanity ascends toward a golden age.

1,200 years ago: The Dragon Prince Anak Araw ascends to the dragon monarchy throne as Dragon King Sol Regem.

1,000 years ago: Sol Regem confronts Ziard, the first dark mage, and threatens Elarion before being blinded with corruption. Luna Tenebris ascends the dragon monarchy throne and expels humanity from the eastern half of Xadia. The archdragons form the Border to keep the two halves of the continent separate.

300 years ago: Luna Tenebris dies without a suitable heir. The Sunfire elf Queen Aditi vanishes before she can resolve the ensuing succession crisis. Aaravos, the "Fallen Star," is defeated and imprisoned by the Archdragons and the Orphan Queen. Avizandum ascends to the dragon monarchy throne.

2 years ago: Avizandum is killed by the human King Harrow. His mate Zubeia ascends the dragon monarchy throne, with their son Azymondias as Dragon Prince.

"Now": Aaravos escapes captivity, but is returned to his heavenly form until his stars realign in 7 years. The archdragons Zubeia, Rex Igneous, and Domina Profundus perish in the battle. Azymondias is the last known living archdragon, and the status of the dragon monarchy is unknown.

and here's things we know happened, but not exactly when:

Between 5,000 and 2,000 years ago: the Startouch elf child Leola teaches humans the secrets of primal magic. Her violation of the Cosmic Order is reported by Dragon Prince Anak Araw, and she is executed for it. Her death forms the Sea of the Castout in Eastern Xadia.

Between 3,000 years ago and 300 years ago: the fang of Shiruakh is forged by humans into the Novablade. At some point, it winds up in the hands of the Celestial elves at the Starscraper.

Between 1,000 years ago and Now: the city of Elarion is either destroyed or naturally falls into ruin. (Anyone who can actually cite a reliable source for Elarion being destroyed is more than welcome to do so, otherwise I will die on the "we have no evidence that Elarion was ever destroyed, actually" hill.)

Sometime before 300 years ago, and probably before 1,000 years ago: the (arch?)dragon Aithne Solaire, mate of Anak Araw/Sol Regem, is killed, by him unwittingly burying her alive in an episode of rage. (I say "probably before 1,000 years ago" because she presumably would have succeeded him as Dragon Queen, if she was alive.)

Between 1,000 years ago and 300 years ago: the modern human kingdoms are founded. The mage wars end as the western half of Xadia is depleted of magical resources. (Unclear whether those two events are directly related.)

Some Speculation: The Archdragons, the Cosmic Order, and Shiruakh/Laurelion

This was originally supposed to be a post about Shiruakh and Laurelion, but let's rewind a bit. We know the Great Ones (a.k.a. the "First Elves") built or instituted something to either create an ideal Cosmic Order or preserve one they had foreseen, because that's what Aaravos wants to destroy as his revenge.

This Cosmic Order seems to be tied to an idealized state of stability—humans acquiring magic is known to be the first step in a descent to "chaos"—but also hierarchy. Archdragons are at the top. Elves venerate them. Humans are lesser beings than both. I think there's a very strong chance that the dragon monarchy was instituted either by the Great Ones, or by some agreement between them and the archdragons. The dragon monarchy oversees and preserves the Cosmic Order while the Great Ones... do whatever it is they do, because they don't actually seem very interested.

Destroying the archdragons (instead of just Sol Regem in particular) could be on Aaravos's agenda simply because they betrayed him 300 years ago, but I suspect they are considered a foundational pillar of the Cosmic Order in some way, and taking out three of the last remaining four was a pretty big win for him. We don't know where archdragons come from—like if a primal has no archdragon, whether one will just... coalesce. If that's the case, it clearly either takes more than 300 years or there's some kind of problem with Luna Tenebris's death and the Moon primal (possible).

Now, as for Shiruakh and Laurelion:

I'm assuming we'll get a translation for Shiruakh's name at some point, the best I could get was Hebrew shir ("song") and ruach/ruakh ("spirit", "breath"). Personally, given Shiruakh's coloration and the fact that her scale empowers Claudia with fire, I would lay money on her being an archdragon of the Sun. Since sometime after her death, Anak Araw is Dragon Prince, a Sun archdragon dynasty on the throne also makes sense. I would also have zero surprise if she was Anak Araw's mother, the mate of the at-the-time Dragon King, just because that would set off some animosity, there. Especially if she was hunted down because of some Cosmic Order bullshit, which would also be delicious—him and Aaravos angry for the same reason.

So why did she and Laurelion fight? Well, we just don't know.

Hmmmm. But no, we don't know.

Now, I would bet that either the Death of the Immortal poem was written long after the actual events, or else large chunks of it are missing, since Kazi skimming over "Laurelion fought an archdragon and its bite killed him" and/or "and then he exploded" would be... kind of weird. The archdragons seem to be aware of what will happen when Aaravos's mortal form dies, so presumably they wouldn't be too keen on delivering a suicidal bite if there are other options available... but the other option is the Novablade, which has the same problem. The Orphan Queen, having the same problem as the main cast, may have "spared" Aaravos less out of some mysterious compassion and more out of also sparing herself and everything in what looks like probably a multi-kilometer radius.

I (and I think a lot of others) had just kind of assumed that Laurelion was targeted for death because of some transgression, but now it seems at least equally likely that he was enforcing the Cosmic Order against Shiruakh going rogue. Given the close relationship that's implied between the archdragons and the Great Ones, with no clear point for it to have soured (except with Aaravos, specifically), it seems unlikely that the archdragons or the elves would feel the need for such a weapon. Which is consistent with the fact that, as we now see in the illustration of Aaravos's tale, the Novablade was actually forged by humans.

Given the trajectory of human civilization over the timeline, I wouldn't expect them to have the technology or knowledge to work draconic ivory that way a thousand years before they acquire primal magic. On the other hand, if Shiruakh's tooth was kicked around for a couple thousand years, why did they suddenly feel the need for a Startouch elf-killing weapon? Is this just a case of dick-swinging, like driving a car that can do 250 MPH when you're never going to go above maybe 90, and that's if you're a huge asshole (which you probably are)? "My sword is made from an archdragon's tooth and can kill a god"?

Was Aaravos behind this, somehow? I would not be at all surprised if Aaravos was behind this, somehow. It's unclear whether one Great One could kill another in single combat, or otherwise force them back to the heavenly plane—if not, the advantages of such a weapon might outweigh the risks for the person with the most motivation to dispatch other Startouch elves. A contingency.

(But I personally also think that Aaravos's manipulation was behind things like... the formation of the Border, so.)

Anyway, since either arc 3 or the leadup to it will presumably involve a lot of frantic researching, maybe we'll finally get some of the Orphan Queen story and learn some of what she figured out.
