Whisper in the Crags (5E)

From publisher blurb:

When the winds blow in from the east at just the right angle, the Whispering Crags north of Lorview howl and moan, giving rise to dark superstition and legends. Little Lottie Fisher has a secret friend who knows more than most about the crags. That strange little girl, drawing her pictures and talking to the dark.

“Lottie has a wanderlust,” her mother Rasel Fisher often says. “Even as a babe on the road, she wandered off for two days into the forest alone. She’s a blessing and a handful.”

What dark secret await the heroes in the city of Lorview this time?
