Everyone in the fishing town of Ilsurian is excited when the legendary Umbra Carnival rolls into town - even if the show is run by members of the much-maligned Varisian ethnic group. With strange and exotic beasts, scandalous performances, games of chance, and all the other fun of a traveling fair, who could resist such an opportunity for entertainment?
Unfortunately for both the town and the circus, however, entertainment isn’t the only opportunity the carnival presents. A group of thieves and scoundrels has been waiting for just such an occasion to launch a campaign of theft and murder - leaving the strangers from the circus and the town to blame each other. With tensions mounting between locals and performers, Chelaxians and Varisians, Erastil's and Desna's followers and with the body count rising on both sides, it’s up to the PCs to uncover what’s really going on and find the culprits before the entire town erupts in a firestorm of ethnic and religious violence.
