One:Chronological Theory

Chronological Theory concerns itself with assigning sequences and compatibility ratings to object interactions.

Presence

Object interactions are classified in terms of presence. For example, objects which can be observed interacting within one cognitive event are said to be co-present. Objects which can be observed within one cognitive event but cannot interact without ending the cognitive event are said to be dis-present. Objects which can be observed within the same cognitive event, regardless of interaction, are said to be poly-present. Objects which preclude the presence of one another are said to be contra-present. The first continuous presence of an object within it's subjective timeline is its protopresence.

The Clock Tower Preservation Society spends a great deal of its time trying to track down the protopresence of the various components of the Balthazar Clock. Notably, many of the components have an indeterminant protopresence as the objects appear to have not yet been constructed.

Nodal Compatibility

A primary component of whether two objects are co- or dis-present is based in the nodal compatibility of said objects. Objects may be polypresent if they are at congruent nodes or anti-nodes of their respective timewaves. As one might expect polypresent objects in an anti-nodal state are often dispresent in a highly disruptive manner (as dramatically demonstrated in the Balthazar Clock Tower Incident).
