Abstract. Prospective Logic Programming is a declarative framework supporting the specification of autonomous agents capable of anticipating and reasoning about hypothetical future scenaria. This capability for prediction is essential for proactive agents working with partial information in dynamically changing environments. The present work explores the use of state-of-the-art declarative non-monotonic reasoning in the field of interactive storytelling and emergent narratives and how it is possible to build an integrated architecture for embedding these reasoning techniques in the simulation of embodied agents in virtual three-dimensional worlds. A concrete graphics supported application prototype was engineered, in order to enact the story of a princess saved by a robot imbued with moral reasoning.
