Story

So as I said before, I think there's four major groups to follow (italics is less concrete than the rest):

Main Characters

These guys are very introspective, usually stumbling into a conflict and having to solve it that way than actively seeking to right wrongs.

Arc 1

• Dai
• Hina
• Karm
• Koray

Arc 2

Arc 3

Native Zirconians

These guys shape every major arc as much as or more than the Voidspawn.

Arc 1

• Dragons are supreme, roaming the world to Kingdom of the Dinosaurs. Bahamut runs a decent ship for them.
• Elves are in hiding, when Dai shows up they think they've got a messiah.
• Are dark fae here? Who knows.

Arc 2

• Dragons are getting fucked since Bahamut's death. There's unofficially some sort of treaty, but there's a lot of active aggression from elves trying to wipe them out. Tiamat offers them sanctuary.
• Elves are on the rebound, trying to end this shit for real. Dai encourage diplomacy, and she's ignored. Devix instead comes forward as a military leader, ready to end this. In time, Dai actively helps end Devix's raids, which of course just weaken her links with any of the more militant ones.

Arc 3

• Dragons are able to get a good foothold with a form of Bahamut back, but zeroes on both sides are fucking things up.
• Elves are largely exhausted and willing to make a deal, but zeroes on both sides fuck things up still a bit.

Voidspawn

Every one of the Voidspawn is about forwarding their goal at any means possible, they're one of the big ignitions for the plot, duh.

Arc 1

• Corvus dedicates his effort to destroying Zirconia, and fails due to the geomancy beneath the surface.
• Shadow dicks around a lot, duh. It's possible this is the arc where he tries to make his family, just to save ourselves from an explosion of characters in the second arc.
• Umbra Obscura gathers freely available information.
• Oh right I should probably note Lugh here too.

Arc 2

• Corvus tries to break the geomancy beneath the surface, creating a bunch of chaos on the surface to distract from his efforts.
• Shadow probably takes a more assertive role, trying to be destructive because well it seems to be working for Corvus. He eventually loses heart, but it's an amazing coincidence he becomes a threat while Corvus is gone. That is, Corvus planned it all along.
• UO allows Corvus to break the seal, only to attack him afterwards and seal some of his power, forcing him to retreat and opening the caverns below for her inspection.

Arc 3

• Corvus is pretty buttmad after the last thing, probably actively seeking out a way to remove UO. He probably doesn't make it out of Eurasia alive, but he'll go down swingin'.
• Shadow starts this arc trying to be good instead. It's hard to say how much this sticks, especially with Corvus starting to crack.
• UO is probably a prime target for Corvus, not to mention she's probably hitting the limits of knowledge she can get while being nice. There's a good chance no one makes it any further.

Agents

These guys are largely reactionary as well, but they ignite some stuff themselves. BURN EVERYTHING was what I saying Arc 1

• Zero Hunter is busted out of the Void somehow after the Voidspawn show up, possibly by Shadow seeing how he has the interest in Dai/Karm.
• Weapon Goddess . . . I'll finish this later, I'll just send this so you have references so some new stuff I've written.
• Tiamat . . . Ditto.
• Fenrir eats stuff.

Arc 2

Arc 3

Miscellaneous

There's a few unaffiliated that have impact (Cim, Devix, Laidena) at some point, if I think of enough they might get their own section. Laidena's arc is mostly she and UO talk until UO's done talking then tries to stop her.
