"It happened around 2,000 years ago, Humanity's glorious ascension, thanks to the scientific enhancement, humanity's 'feelings' were abandoned, we became a race of glorious scientific beings, advanced in all forms, and anything we deemed 'useless' was abandoned, love, hate, dreams, hope. we have become the ultimate race... but there is a rumour going around.
as you should know, when we are born, our children sadly still have useless traits, such as 'love', so all children are subject to mandatory ascension. the rumour is that there are some who don't ascend, abnormalities in the number of humans... these abnormals are hunted down, and killed."
WARNING! WARNING! ABNORMALS DETECTED IN THE AREA! EXTERMINATE ON SIGHT
"w-w-what? YOU'RE AN ABNORMAL? OVER HERE! THEY'RE OVER HERE!"
Humanity has become machines, highly efficient machines without feeling or thought to life, but not you. you are one of the 'abnormals', humans that are immune to 'ascension', you are kill-on-sight types... you have feelings, thoughts, you can be lazy, happy, sad, etc. you have feelings and free thought... and that's why you;re considered 'useless'
Humans no longer have names of their own, 'useless limited characters', humans now have codes for names. and you're no different, however, some Abnormals have taken to the traditional human ways, to name themselves. but when hiding in public, you must use the codes.
Abnormals are hidden among others, your neighbor could be an abnormal, your boss, your children, but if anyone finds out... they'll be hunted down. Abnormals can be detected around the authorities, human given protocol and higher power than most, so if you're an abnormal, be careful.
oh! before I go, there's a rumour going around that Abnormals are gathering to start an uprising... If you wanna join, that's good, don't bother looking for them... they'll find you.
