From the Introduction: This book contains the rules that you will need to play your character at an event. You need to ensure that you are familiar with these rules so that you can understand how to act at events. Your character will not be able to use all the combat and magic calls described in these rules, but you need to know how to react to these calls in case they are used on your character. This book complements Character Creation, which contains everything you need to create a character. Some minor updates have been made since that book was first published and the Event Rules takes precedence in the case of any conflict between the two books.
