From Unofficial Handbook of the Virtue Universe
Luck is the force that seems to operate for good or ill in a person's life, as in shaping circumstances, events, or opportunities and/or is a matter of having something good or bad happen that lies outside the horizon of effective foreseeability. Luck thus always incorporates a normative element of good or bad: someone must be affected positively or negatively by an event before its realization can properly be called lucky.
Luck has three aspects: (1) a beneficiary or maleficiary, (2) a development that is benign (positive) or malign (negative) from the stand point of the interests of the affected individual, and that, moreover, (3) is fortuitous (unexpected, chancy, unforeseeable.)
Luck refers to that which happens to a person beyond that person's control. This view incorporates phenomena that are chance happenings, a person's place of birth for example, but where there is no uncertainty involved, or where the uncertainty is irrelevant. Within this framework one can differentiate between three different types of luck:
- Constitutional luck, that is, luck with factors that cannot be changed. Place of birth and genetic constitution are typical examples.
- Circumstantial luck—with factors that are haphazardly brought on. Accidents and epidemics are typical examples.
- Ignorance luck, that is, luck with factors one does not know about. Examples can be identified only in hindsight.
Lucky could include characters that are able to consciously or subsconsciously use pyschic powers to sway probability in their favor.
