2.4 Defining the Undefined
This book does not attempt to include specific rules for every aspect of a realistic world. Unless defined otherwise - or if it’s not worth the effort to look up Rise’s exact rules in the flow of a game - you should assume that the universe works more or less like the real world does, and as long as everyone agrees that something is reasonable, it’s not worth worrying about in more detail.
For example, Rise does not have specific rules for how long it takes to eat a meal, the arc that a thrown ball takes through the air, or how much extra weight a well-made chandelier can hold without breaking. It’s possible to imagine situations where each of those might be important to a game, however, so you’ll have to guess what would be reasonable as obscure situations arise. The Game Master has the final word when defining ambiguities like this.
2.4.1 Resolving Ambiguity
When the rules are ambiguous about how they apply to you and no other creature, you decide how to resolve that ambiguity. For example, if an ability causes you to remove one of your vital wounds, and you have more than one vital wound, you choose which vital wound is removed. When the rules are ambiguous in any other situation, the GM decides how to resolve that ambiguity. This includes situations where multiple creatures are relevant and situations where no particular creature is relevant.
