Change is the process whereby some or all of the properties of a Thing, or the characteristics of a Being, are added to or subtracted from. Change happens in three ways:
- The effect of Time upon the Things or the Beings;
- The effect of Work performed by you or your spouse upon the environment in Anesidore;
- The effect of Talon exerting His Will upon any part of the Vast, including any Thing or any Being.
Generally, if change, regardless of the source, causes a Thing to move past its systole or diastole, it becomes some Thing else. Likewise, if change causes a Being to move past its systole or diastole, it becomes a different Being.
