This book contains the rules that you will need to create a character. You will only need to refer to these rules when you are making a character; you will not need to remember all of these details during an event.
Two books acompany this one. The Introduction To Live Roleplaying explains live roleplaying and describes the approach used at our events. The Almanac Of The Known World contais detailed information about the world the game is set in.
After you have booked for your first event, you will receive two additional books. The Event Rules contains all the rules that you must follow when role-playing at events. The Downtime Guide gives information on how to use the downtime system to further your character's objectives in between events.
