Dimensional Box

I created this box to open a small window into another dimension, I was experimenting with locating new dimensions never transversed by any known being. Worlds farther away from mine in the multi-verse. This resulted in finding a dimension where its inhabitants were not satisfied with staying where they originate from. This creature in particular wanted to come into this world and spread itís madness. I could not let it become free in this reality so I was able to stop it in time, literally.
