Etheric Miles

are units of length used to measure distances in the ether.
== Context For Distances ==
Spaceships usually travel through the ether at speeds of anywhere from 20 to 200 etheric miles per hour. The average density of pocket dimensions along an etheric ley line is 1 world per 2,500 to 4,000 etheric miles (although the actual spacing between any specific pair of neighboring worlds may be much larger or smaller than this).
