Historical Importance Index is a mechanism in the Shadow Fight world which allows all people to change the course of world history processes with their wishes, thus being able to change the face of the world based on their personality. Because everybody has access to this power, more often than not their wishes will intercept and clash with each other over which one gets to become reality. The winner whose wish will triumph over the one of his adversary is the one who is simply more important to the world than the other. This is why people who are very important will change the fate of the world with their wishes so suddenly they won't even know how they succeeded so easily, because they don't even have to try much, while those who are less important than the previously mentioned won't be able to change the world with their wishes even if they try harder than the more important people to make them reality, their wishes getting completely overwritten by those of the more important individuals. One's historical importance index is as high as how many other lives they impacted, and how dramatically. The higher the index of historical importance of a person is, the more "luck" they get in all their plans, the more of their wishes will come true.
