Rift Navigation

Rift Forces use a sub-dimensional vibration called the Word which can be heard throughout the Alterverse (or, more precisely, all the sections of the Alterverse explored thus far). No one knows what the Word is really made of but it manifests itself periodically as a rare type of exotic particle known as Lexis7. 
By calculating the vibrations, Rift Forces can differentiate between individual dimensions, making organized travel across the Alterverse possible. Each dimension is given a sequential numerical identifier, consisting of 9 digits and 3 letters. Home (this Earth, the original Earth of Rift Forces) is designated ABC-000 000 001.
Much of Project Dark Horse's operations has consisted in mapping out the Alterverse and designating newly discovered dimensions.
