Inside a cast member will walk you through the process and set up an account attaching it to your park ticket or magic band. You can have multiple tickets/bands attached to one account. By doing this each member of your party can receive a deck of cards every day they check in. Each pack contains 5 spell cards with a total if 70 cards.
Here is a Cast Member training my son.
Once you have your spell cards, map and key card (main card that identifies you) your ready for your first mission.
All locations are randomly generated by the computer system. Certain cast members are willing to input a location for you. This was great for us when we were only an hour from park closing and stopped at the Sorcerer's location in Liberty Square.
The 4 areas are:
Liberty Square and Frontierland
At the end of each mask location it will show a picture of the next location as well as a symbol which will help you locate it on the map.
Since there are 70 cards available you have many options to choose from when it comes time to casting your spell.
