Thieves of Earfell

From publisher blurb:

A light-hearted 5E-Compatible Adventure for characters of levels 2 – 5.

The adventure starts when the player characters arrive into a small village of Payala next to a mountain range and large hills. A smallish mountain only a few miles away from the village looks a bit unusual as it happens to resemble a pointy ear – the mountain is called Earfell and a clan of redcaps hides somewhere in its maze-like valleys and caves.

The adventurers are hired by a retired toymaker, Santor Claos, to retrieve his stolen stockpile of toys. Soon after the adventurers enter the redcaps' lair, they will find out that something is very wrong...
