The Follower
Here is a completely standard introduction, so standard that it simply kills with its banality. The System comes into the world. What follows is equally banal. The System announces to those few who received it first that soon the world will come to a full-fledged Apocalypse, Hell-on-Earth, and other blessings. According to all the same dead cliches, the Main Character must begin feverishly leveling up and saving the world, using his perks, imbalances, and super-abilities. And it seems you have all of the above - perks, unique talents, and accelerated leveling... but you are not the Main Character. You have no idea how exactly to save the world, look for answers to the Secret Questions, and all that. You are not a fearless vanguard fighter, not a veteran of Mossad, Alpha, and Delta at once, not a hero at all.
In this story, you are not the one leading the way, no.
You are just a follower.
