Well...here's my thought process regarding the cure. We talked about my Aether-flower idea before, but what are the dragons going to do, eat them? Seraphine wouldn't like that. Aether-flowers likely have large concentrations of Aether around them, so instead of eating the flower, the mere presence of Aether in the area should be enough to heal wounds and reverse the effects of the fog. My second idea was to have them discover the Aetherswell, but you already used that idea in your role-play and I don't think it works nearly as well here as it did there.
When Seraphine discovers an aether-flower, there will be some character development and a moment of reflection. I think once she is healed, she will return to Arcstorm and Torthai and share her findings.
And here's one more thing that I was wondering about. Seraphine obviously saw something move in the trees, but it wasn't Torthai. I think she actually saw a glimmer of Aether that's trying to lead her to the source (the flower). My question is, where did the Aether come from? Well, in Aetherlight, it usually comes from doing things to help others. There was a lot of that going on in the earlier fight—Seraphine, Velika, and Arcstorm tag-teaming to fight Abraxas, and especially Everest (@Rex_Blackdash) sacrificing himself to let Torthai go free. I don't know if I'll actually be able to incorporate that into the role-play, but it was just an interesting idea I had.
@Titan_Candleburst, @Lilliana_Umbrellascope, Great skies, you guys write faster than I can keep up. I don't want to quash your inspiration, but maybe you could tone it down a little?
