Construct

A construct is a conceptual structure which gives form and properties to psi energy, through which psi energy flows, and which manifests the intent of the psion.

Constructs can take a simple structural form, such as the psiball, or they can have a programmed behavior, such as some psi shields or more "thinking" constructs like the watcher. Constructs are a separable creation, able to operate the intent placed within them long after the psion's attention is elsewhere.
