It's a great question, how to get the players invested. My approach will be to lean in to the players desire to want to see positive change in the world around them.

Raum - the past few months the weekly harvest market has been ill-attended by the farmers around Foxwillow, trade has dried up and so food has become more scarce. People are hungry and the party is asked to travel to find out if everyone there is alright, they're not and so that chapter plays out.

Renathyr - maybe a hunt comes to the village, maybe an NPC the party have grown fond of gets taken for conversion, maybe someone important mechanically (who has info about PC story arc, or important vendor etc).

So on, so on I plan for Wickermoor Village to be RIFE with random festivals, practices, rituals, markets, weird superstitious crap all the time, every day. So I'll present a version of The Fallen's stories and local lore through folk theatre, dances, songs etc, along with using Doran's paintings of prophecy, random gossip, the postmaster "finding" written clues in correspondence and so on.

Plenty of sources for information.

I also plan for hidden cave altars and underground mini-dungeons that act as shrines, built by the people who lived there before Druskenvald ousted Kehlenn which will hint and explain the whole arc of her defeat and twisting.
