Systems for interactive storytelling and drama rely on agent theories to model characters, and adopt various techniques to cope with non-determinism at the story level, such as story models, combining them according to sophisticate architectural designs. However, a consolidated approach has not emerged yet, that fully reconciles these two dimensions. In this paper, we propose a unifying framework to accommodate the tension between story control and character behavior. By using a model of agent to analyze a classical example, we show that this tension cannot be solved by discharging the distinguishing properties of agency. Rather, we claim that the accurate modeling of agency is a prerequisite to the success of any attempt to solve this tension, together with the possibility for the author to state the story direction in terms of explicitly declared values.

Abstract
Systems for interactive storytelling and drama rely on agent theories to model characters, and adopt various techniques to cope with non-determinism at the story level, such as story models, combining them according to sophisticate architectural designs. However, a consolidated approach has not emerged yet, that fully reconciles these two dimensions. In this paper, we propose a unifying framework to accommodate the tension between story control and character behavior. By using a model of agent to analyze a classical example, we show that this tension cannot be solved by discharging the distinguishing properties of agency. Rather, we claim that the accurate modeling of agency is a prerequisite to the success of any attempt to solve this tension, together with the possibility for the author to state the story direction in terms of explicitly declared values.
