Rift



The use of doors, however, destabilizes and weakens space-time nearby. These unstable, pulsing tears in reality are called Rifts. A rift represents a weakening in reality, and "points" to a specific location, whether that be a pocket dimension, another place in the overworld, or even in the Nether. Sometimes the destination of a rift will have another rift that leads back, sometimes they do not. Regardless, placing a Dimensional Door over a rift will open a passage to whatever is on the other side.

They are created in several ways- A dimensional door, when placed, creates a rift at that location. The door also "contains" said rift. They appear randomly in the world, and when grouped together, they can spread. When naturally generated, they often contain dungeons and other ruins.To further manipulate these rifts, you also have the Rift Signature and the Rift Remover. But be warned- several rifts in close proximity have a tendency to spread, and endermen have been know to use these rifts to enter from the end...
