Who created it? Nobody knows, it is a foundation for all that lives today. Whoever created this universe has used that evil for building blocks. It is not chaos, it is simply darkness, the creatures leaving within it have only two functions, consume and reproduce. They have no individuality, the Uknown controlls them all, they are it and it is them. Its mission is clear, it wants to be whole again, by absorbing the matter from which we exist expanding itself. We are a disturbance in its infinite body, it wants to eliminate us for that reason. It has no known weakness, its forces are infinite, those like me have kept the border between our reality and the Uknown secure, as long as there was a border to keep. They were given great powers, powers to bend reality to their will by the creator, but they were also given great limitations, in order to interfere with other forms of life, they have to gain a physical form and their power would be greatly reduced. That is what i am right now.
What we are about to deal with is only a small particle in the body of the beast which is the Great Unkown, but this particle can and will destroy our whole universe if it is not stopped. Once it falls on this planet, the hordes of the Unknown will start to reproduce and consume, soon they will cover all of the land and wrap the whole planet into the blanket of darkness, then we don't know what happens, but we seen it before. Somehow the magical connections between the world and the astral are broken and the world falls apart becoming the same material from which it was created, the Unknown, once that happens it begins to spread.
A particale this big has never before been allowed to break through the defenses. The only way to stop it is to break its link with the Great Unknown if that happens our reality will absorb the dark matter. Only i can do that, but i will need help, upon impact a great dark stone will be created, it is the medium between the unknown and its minions, i will need help to get to it, close enough to touch it. There is no way of knowing there it will land. I can not fend off all the minions myself in this form. I will need you to help me.
You know what is required of you. Who shall choose to go with me and meet this doom head on, facing a most certain death and who shall choose to live, knowing that the world will fall apart in a matter of months?
