Action Points & commitments
AP is a replenishing Keeper reserve. Commitments are timed actions already underway.
Action Points, usually written as AP, are spent to begin certain actions. One AP returns every 30 minutes until your current maximum is full. A commitment is a timed action that has already begun and has not yet settled or been cancelled.
Spending and recovering AP
Any posting or action that costs AP shows the amount before you begin. You need at least that much AP available at the moment of initiation.
AP then returns automatically at one point every 30 minutes until your current maximum is reached. Your current AP and maximum are part of the Keeper record.
What a commitment occupies
Work, creature training, Rest, clinic care, Play, and Journeys can create timed commitments. Some may overlap; others cannot use the same Keeper or creature at the same time.
Current commitments show their remaining time together. When the recorded completion time is reached, settlement applies the result: rewards, recovery, history entries, or whatever else the posting promised.
Cancellation
Cancellation follows the terms of the commitment you started. An unfinished action may lose its reward, return only part of a cost, charge a fee, or carry another stated consequence.
Read those terms before cancelling. The consequence belongs to that action, not to timed commitments in general.
