Prologue

Time is complicated. These complications differ depending on the length of time being dealt with. In a few hours, few things can happen to any one person, so the consequences may appear before the time stream rights itself. Days or years, however, are extremely complicated. The consequences of ever action makes a change, and many days or months of changes are impossible to predict. For this reason, long-term changes are never visible until the end of the quest. There is therefore no guarantee of safety or success when dealing with long-term time, as the consequences are not yet visible as they are with mere hours of change.
