this happens when a lot of people have a certain hero and named after him or legally change their name to them and may even share the same birthday and have the same features like skin color and height or description. and it could be for many reasons like their greatest role model, or the person name gives them protection against attackers, or they really love the name more than they own and the original such a good day: that he don't mind either. for an example the name John Smith is so vast and plentiful all around the world and it's counter part Jane Smith for female. it's really great experience hearing all the great stories on how it unfolds so specially for each person and always more is added indirectly and independently it's not a conspiracy or anything like that. purely coincidence probably the only one too.
The Neegin Collection or The Neegin Experience is something most people wouldn't care about learning because it's so mundane but to the few who loves to adventure or explore it's a nice little side quest or side adventure.
