The Kroth Magg hobgoblins run the trade city of Glip Dak in the Troll Hills of Thar. From there they have taken control of the trade routes along the northern Moonsea. A young noble has been captured for refusing to pay their tariffs and his house looks to hire adventurers to rescue him.

The adventurers are tasked with rescuing a group of heroes who vanished in the pearlescent fortress that manifested on the border between the Kroth Magg kingdom and the Varkonin empire in the Steppes of Thar.

A behir has been hired to destroy the herds of aurochs necessary to feed the hobgoblin city of Glip Dak. Patrols and scouts continue to go missing, forcing the hobgoblins to hire mercenaries to track this behir as they recall their troops to the capital to maintain order as food riots break out.

A series of unusual heists has both the thieves’ guild and city guard scrambling to uncover the culprits before the burglaries destabilize the thriving trade within the city, threatening the budding kingdom the Kroth Magg have fought and died to forge.
