The names of many legendary swords reverberate through history, and these swords often were carried into heroic, at times revolutionary, struggles. Some have considered the swords of these tales the source of the Honedge, but if that is the case, their legend does not end with death, for it only reaches its apex with their final evolution. By the time they fully evolve, Aegislash are already dominant on the battlefield, but power and victory alone can no longer satisfy them; instead, they recall their time warring as Honedge, and wish to once again change the world.

Aegislash can exert a powerful influence over their trainers, and are capable of using their legendary reputation and a power of suggestion - bordering on mind control - to manipulate people around them. They do this to ensure that they wind up in the hands of kings, which they accomplish most often through heroic quests which culminate in a new king; they will aid established monarchs only when their kingdom faces dire trouble and consider the struggling kings worthy, and they exploit the aid they provide to ingratiate themselves with royalty.

Aegislash appear to have altered world events primarily as kingmakers, although to be sure few kings would inform others they took advice primarily from their pokemon. But the minds of kings they have chosen to rule were often very much like the Aegislash's anyway, and the Aegislash at least believe that through gratitude they influenced their royal wielders to change the world for the better.

Of course, changing the world for the better is itself a difficult thing to define, and wars have often been fought over said differences of opinion. But there are few who would question the joy omnipresent in modern Kalos, or the role of Aegislash in getting Kalos there.
