This document describes all formulas and processes used in PHost. It is intended for players who do not leave anything to chance. If you believe that some aspect of PHost operation should be documented in this file but is not, send mail to the PHost group and bring this to our attention.

This document is roughly grouped by the major object of an action. For example, Pillage is a mission that affects planets, and is therefore documented in the Planets section. If possible, formulas are arranged in the order they are needed during host processing. The exact sequence of events is documented on the Host Sequence page.
