idk
I'd like to see this as a background conflict that you hear about in the next few games, so it feels suitable epic and universe changing? Or a Laez themed DLC adventure, set decades later covering the end? but not to have it, finish quickly as a side adventure to the absolute? it feels to be big for this treatment to me?

Minthara is the best character and she NEEDS to be recruitable if you side with the grove!
Also- I support the important thread in the suggestions: Let everyone in the Party Speak
