Icewind Dale: Cult of the Shattered Peak

This 34-page Rime of the Frostmaiden add-on brings to life a cunning network of cultists that run clandestine operations in plain view throughout Faerûn. As players delve into the secrets of the black obelisks and the remnants of the ancient empire Netheril, the descendents of Netheril will stop at nothing to ascertain that the ancient empire’s secrets are never uncovered—even if that means pressing blade and spell to your party’s throats...

...or, perhaps, entice them to the cult’s side.

In this supplement, you’ll find everything you need to integrate the Cult of the Shattered Peak seamlessly into your Icewind Dale campaign.
