He told me all about them.
The Agents. Guardians of the System. Impossible to defeat alone, and extremely difficult to beat in groups. It took planning, strategy, and the will to survive an encounter that was never to be forgotten.
I have always been afraid of these Agents. Not because they are intimidating by appearance, but because of the stories that surround them, that an Agent can literally dodge an entire machinegun worth of bullets, can punch through a solid concrete wall... it makes me wonder if I, too, will face such a being in my time. That I might be forced to battle an Agent of the System, at some point. If this happens, I certainly hope that I am well prepared, with my friends close by me.
There are, of course, other things. I have seem strange corrupted programs running amok. Black, foggy creatures, standing well over my height. I cannot tell if these are glitches in the system, or the outside work of some other devious being, but I narrowly escaped with my life intact.
There are many amazing things within the System that I have yet to witness, and it is in these trials and journeys with him that I will learn about the system, about the secrets within it, and unlock the door so that I may finally walk through it, for the first true time in my life.
