  In this text, we consider the authoring of interactive digital narratives
(IDNs) as a system of interwoven creative processes and look at it as a design
process. The aim is to better understand the structural, aesthetic and
interactive concepts authoring has to address, how authors think about those
and what that means regarding the tools required to support authoring for IDNs.
The paper concludes with a detailed vision of an authoring environment that is
considered an open-source sandbox system, which provides the technical means to
build a functional IDN but adapts the availability of technology based on the
narrative engineer's aims, goals and skills. The environment establishes a
collaboration between itself and the narrative engineer, who's interaction on
one side focusses on the collection of material and its classification and on
the other side covers the design of the engine that facilitates the aimed for
audience to establish the stories for their information need out of the
provided proto-narrative content space.
