Stone Soules Summary: Aftermath of Alegra's Rescue
Gerald is happy to get Alegra back safely and was worried about her. Especially after ensuring her identity, he simultaneously warns her to be more careful and congratulates her wisdom in surviving.
Gerald suggests various preparations in case the demon-worshippers attack us and/or Middle. First, realize that everyone (practically) hates demons. Second, don't scare the populace of Middle. Third, don't make people angry at us by making them think we incited the demon-worshippers to anger.
On the first point, the various churches in Middle (you have mentioned several) should be willing to help out. Decide whether or not to enlist their help. Just keep the second and third points in mind.
On personal preparation, we should consider magics available:
Alegra can prepare Glyphs of Warding on small items to give us of us as well as place around strategic points. She may be able to cast Divination to learn more info. Depending on what the demonspawn are, if she can Abjure them it's nice. If she can Implore (reversed Abjure) a servant of Phaulkon to help fight the demonspawn, it would be of great use and conceivably relevant to the angel (or whatever).
Dari can probably cast useful third-level spells of strategic use: Plant Growth, Snare, and Stone Shape have permanent effects. If she is 6th level, Hallucinatory Forest also has a nice strategic use, especially if combined with Plant Growth. Protection from Lightning would be great against the beithir.
Gerald can help set traps if you want to do that, and Ludo might be able to as well. (Though Gerald's probably better at the kind of outdoor traps I have in mind.)
The "everyone" that hates demons includes other adventurers. There's a friendly group at Koralgesh, and we could tell them we are friends of Gram. King Ranore and Duke Konrad are a bit far off, but they might send someone to help out. Other opportunities abound, though we might not need (or want) any help at all.
