Each MISTI-Con has been developed based on"in universe" theme that serves as the backdrop for the immersive experience, the decorations and the program booklet.
In 2013, the Minister of Magic authorized the creation of MISTI-Con. A center designed to find the brightest, most talented wizards to fill the positions of the many staff lost in the second Wizarding War. After the success of this event, with our strength renewed, the Minister declared a new initiative to repair relations with our wizarding brethren around the world, MISTI-Con 2015: The Wizarding World’s Fair.
In 2017, in remembrance of the 20th anniversary of the publication of the the Wizard History book, Harry Potter and the Philosopher's Stone, the Ministry decreed that the Service Training Initiative recreate the environment and details of the world as seen through the time many of us first encountered the material — the locations, events, and stories described therein.
For 2019, The Ministry's interest has become focused on the idea of time, both the past and the future and so the Service Training Institute has once again been called. This time to explore all of the amazing past accomplishments and the future developments of the Wizarding World, thus the MISTI-Con 2019 theme is "Wizarding Through the Ages"!
