This is a part of the Disambiguation Template. Edit it with great caution.
This piece of the template is the central location for converting the Earth-# to a short name for the reality. Feel free to add missing ones, but be sure to put them in the correct sub-template page.
For instance, if a reality came up with the number 11111, you'd go to Template:Number to Name/5, since the reality number is 5 digits long, and enter it numerically in that list. Be sure to link the description to the first appearance of the reality as a good jumping off point for the casual browser.
