Quite possibly!
The “Secret Theurge” path will to some extent need to be a part of each game where you could for the first time hit INT 2. But the “gate” where I write you into a situation that can only be resolved with a public display will likely come earlier.
Very little. You’re not going to be able to develop entirely new types of air-arm. Anti-Plektoi bullets are a possibility.
For now, let’s just say that you are definitely not going to stumble onto an unclaimed stash of Talismans that lets you assign them to whoever you like.
Jev is definitely a more plausible candidate for future leadership than Alaine is.
The Hegemony-Halassur war isn’t set up to be won by military valor on either side. It’s locked into a grinding stalemate that will eat up lives until one side or the other gives up.
I don’t think your faction will end up HQ’d in an old mine.
Cerlota is not herself a poet, but Carles would confirm the artistic calibre of the great Erreziano poets.
I’ll write more about Dilek later – maybe not “classified until game release” but for a little while yet.
No. Trying to give living organisms all the key features of a Harrower is likely impossible, and even if achieved, you’d have a Harrower that (a) required massive blood expenditure to create, (b) would need constant feeding and guarding to keep it from wandering off, and (c) would die before too long. The economics just don’t work out, I’m afraid.
Heh, that’s a nice idea. I’m not sure it’ll be possible, but if so, I’ll definitely give it an achievement.
Baneforged? 
Someone’s an Infinite Sea fan.
No, those get used up one way or another, if you have them. The only Theurge-forged item you have a chance of retaining into G2 is the sword.
The folk of the Reach always said “Xthonos,” a borrowing from the Karagond culture that infused their own, and they had converted the rest of Shayard before the conquest.
This is accurate. But if you save them without tying them up, they can accompany you into Game 2.
