Phases

A phase is not a destination in
itself, but an invisible sub-dimension
of one specific reality. Unlike an inter-
penetrating plane, it is not distinct
from its partner reality; it merely rep-
resents a physical or supernatural
“wavelength” different from the stan-
dard one. The main use of such realms
in fiction is to let travelers rapidly
bridge the gap between two locations
within the same physical reality.
An example of a phase is the ethe-
real
state
that
those
with
Insubstantiality (p. 62) assume in
order to walk through physical obsta-
cles. Another example, common in sci-
ence fiction, is hyperspace: the “space”
into which stardrives shift starships
for faster-than-light travel.
