The attack on Gotham was a long, and difficult one.
To understand why Select Few did what they do, you need to first know of their origins.
Select few is one of the many organizations tied to the league of shadows/the league of Assassins. They are split, into hierarchies. There are perhaps around a hundred members in the top circle worldwide. No one truly knows their goals, but most of the middle group prefers to think that it is to cleanse the world of crime and corruption- or just to cleanse the world.
It is said that the group consists of anyone from politicians to rock stars- that is not true. To join the top at Select Few, you needed to pass three initial initiations of compatibility. and six further tests, on strength, power, mind, spirituality, speed, knowledge.
Only the best of the best, selected first from the masses and then from the middle could hope to push into the elite.
Then there is the mediators. The middlemen, the group that links the top to the masses that follow. They are the believers, the true worshipers of whatever words the top spews at them. They range from small business owners to vastly wealthy but low key people. They are given a small amount of control over the masses, but seems to think that they, personally will be chosen into the elite top- they are delusional. There are around three thousand of them around the world- still a small number.
And there are what they call the masses. There are around nine thousand of those people,perhaps more. They are the general, everyday people we would meet. Of course, they must have something to offer to Select Few- skills like public speaking, hacking, mastering of various technologies, martial arts any skill set that are useful to Select Few are utilized. Some are veterans, most have physical training.
Now, you ask- but what are their motives? Why do they join? Well, the answer is that they do not 'join.' Each member, ever since the group is founded, is selected by one of the top- then they select other members, approaching them in secrets and dragging average, well to do citizens into this fascinating, but terrifying cult. Sometimes people join, not out of willingness, but out of fear. Fear for their lives, and the lives of their families.
On top of the elite hundred, there are thirty three finalist members. One of them is the current leader of Select Few, the others possible candidates for the next.
The organization is said to be thriving for hundreds of years, and the only thing that has changed is the skill sets needed for joining. The current leader is the thirty- third leader- a perfect time, the group states- a perfect time for the final revolution.
And that brings us to their motivation. What does a vast and powerful organization like Select Few want? Certainly not world peace and the irradication of crime and criminals and poverty like the masses and even the middlemen believed.
No. No matter what any, any powerful organization's original goals were, it was destined to become lost- lost in man's greed. Greed for money, for power, for the world.
And it was with such a greed that Select Few, this terrible and powerful group of men and women, launched their attack on Gotham.
