"The Alchemists' Guildhall" is a rusalka lair suitable for four or five 6th-level characters. This adventure can be completed in one session.

There is no night for faeries and the fey like Midsummer’s Eve, and the green woods hide many wondrous and magical things on the shortest night of the year. On this night, a group of curious villagers would be adventurers, perhaps wander into the forest and encounter the lonely rusalka, who asks for their help retrieving her lost heart before the night is done. Pgs. 7-14

The small village of Jaromir seems beset by a powerful curse. For the past twelve days anyone who enters the forest is never seen again.

Pgs. 15-19
