As an exercise, I want to challenge the forum to take some of these hooks and flesh them out a bit (250 words or less I think is fair) into Bad D&D Plot Summaries or something like that??
So I’ll start:
The PCs hear that the town of Neverwinter has been ravaged by what sounds like the machinations of a death cult. Large swaths of the population have taken their own lives after entering some sort of trance, leading the party to believe that demons have possessed the townsfolk and driven them to this. In order to learn more about this happening, the party charters a cart to take them to Skullport where they can hopefully find a shady character to teach them about demonic magic. En route, however, they receive a Sending spell that informs them that Waterdeep has suffered a similar fate. One of the PCs, thinking that this sounds awfully familiar to them, suggests that the flora in Faerun may be evolving to attack the people living there. Investigation is surely warranted, and thankfully, a druid is in the party. The PCs cast Speak with Plants and, unsurprisingly, learn very little.
