There once was a tale of a giant, a terrible giant, that claimed he built great gates to connect other planes of existence to cause devastaion in the world. No one know where the gates came from, they only know that they are there. Four in total span the earth. One in the east, another to the west, one up north, and its parallel to the south. The gates are equal in size, length, width, and height, but each have their own unique etchings on the face. The etchings are not as important as what seems to come out of the gate, for once they open monsters spill into our world. All kinds show their faces at random openings, some look like spliced animals while other are unrecognizable, but they all are considered hostile and a danger to human kind. Some on earth believe  that it is demons coming forth for the end of time, and many believe it is just a natural occurrence that has always been, but then again what do people really know anyway.
