From publisher blurb:
There exists a long-abandoned chapel that once belonged to the Order of the Infinite Step, a cult that worshipped Istim the Unseen, a djinni king of extraordinary power who is said to rule vast regions of the Elemental Plane of Air. It was fashioned with sonorous rock formations that played hymn-like tunes when the wind blew just right. Over time, the ruins grew quieter but now what sound they do produce escapes as eerie eolian echoes. Recently, some research emerged identifying the chapel’s site and suggests treasures still lie somewhere in its remains. These valuables are sought after by more than just curious adventurers. The scholar initially planned to hide his discovery until he could put together an expedition party to visit the site, but things have changed. Not all faiths are as dead as they appear, and the Infinite Step has sensitive ears.
Echoes of the Tempest is a Q-Encounter, or Quick-Encounter, that can be run for a group of four to six players with 7th-level characters or higher. This encounter would be considered a ‘medium’ to ‘hard’ encounter.
