ESCAPING WIDESPREAD DISASTER
FORMS THIS MIGHT TAKE:
HUMAN NEED DRIVING THE GOAL (INNER MOTIVATION):
Safety and Security: When disaster strikes, it is typically immediate. And if it's not, forecasting with accuracy the level of devastation is almost impossible. So fleeing the area is usually the best course of action. Once beyond range of the event and its aftereffects, security resources are easier to obtain, and balance will be restored.
Physiological Needs: Disasters can cause high mortality rates for those who are unprepared or unequipped to deal with them. When a character believes their life is at stake, fleeing is the usually a good idea.
