"Hail Traveler!

We bring a message from the Kingdom of SCIT! The crown requests your attendance on the eve of the Fifteenth Day in April. We must embark on a quest, which is yet to be revealed, however we are certain you will be able to provide us with some inspiration to start our journey. We are aware your knowledge of Locations and Events is far superior to any normal person. 

With your suggestions, we shall begin our quest where we will experience the adventure of a lifetime! Watch as our story unfolds, relationships develop and consequences are determined by a giant inflatable D20!

As with all adventures, seating is limited so the crown requests that you order your ticket ahead of time to secure your spot in this quest. Be assured, you will not want to miss this!"
