The Other World

The Other World is an extraordinarily dangerous parallel dimension that is believed to be 1 dimension in a suspected number of 6 alternate dimensions. Although there could be more than that.

Description
The Other World is a dark reflection of Earth. That is the best way to put it, as you can't really describe the feeling of unusual dread when you take a look at it. It is a completely dark dimension. Not pitch black, but not very visible unless you had a lantern. It seems like it is night all the time there, but there is no moon, or... sun.
