Below is the TL;DR version of a review I posted at http://takeonrules.com/2014/08/03/thulian--
Zzarchov is crafting adventures that are more than backstory, set encounters, and random encounters. In Thulian Echoes, Zzarchov focuses on the knowledge transfer of in-game information to the characters by way of the players playing different characters.
I found the adventure inspiring and interesting. I both want to run the adventure and take the procedures and work on my own. So for my purposes, Thulian Echoes is a resounding “must have”.
