After a botched Lizardfolk ritual left his people stranded in the Prime Material, Coriander Thorn decided to spend his decades with intention. The Fairy made a name for himself as the "Don" of the Glitterati, which would grow into one of western Commona's most notorious crime gangs. In his dealings, he became familiar with all manner of law enforcement across the Fencrest Foothills, and even more familiar with the region's criminals.

Having long known of their hoard, but only now possessing an idea of where to find it, the Don sought to collect the key from Bleak End. If his sources were right, the Glitterati would have enough wealth to buy several kingdoms; but the Glitterati were planning something much, much grander than that.
