Phases of the moon.

I was discussing the phases of the red moon with a friend over the weekend
and want to check the validity of the conclusions we came to.

As I understand it, half the moon is red, the other half is black. As the
moon rotates, an arc of red moonlight sweeps outwards across Genertela.
Outside the glowline, the red moon is seen to wax and wane over a 7 day
cycle from full, to black, to full again.

The situation in Glamour is quite different. Looking up from underneath
the moon, you see a circle that is half red and half black. The dividing
line goes right down the middle, so Glamour always gets the same amount of
moonlight.

My friend said that he believed that inside the glowline, the moon is
always full. This makes little sense. The moon rune is clearly divided
into two parts, presumably showing the moon as it appears from Glamour.

The moon is inherently cyclical, surely this should be apparent throughout
the empire?

My sugestion was that the glowline bounds that area under the moon from
which at least some of the light side of the moon is always visible. Near
the glowline it would only be a narrow sliver of light at the bottom of
the lunar sphere during the darkest phase, but enough that the flow of

moonlight would be continuous. It is this continuity that provides the
benefits gained by lunar magicians inside the glowline. Lunar magic
outside the glowline is weaker because of the periodic disruption in the
flow of lunar light. As the moon ascends higher into the sky, the glowline
would expand as the under side of the moon would be visible from further
away.

Sorry if this is old hat, but the idea that the moon inside the glowline
is always full seems a bit odd. I don't mean that from a physical points
of view, I'm quite happy to accept it if there is a good mythical/magical
reason for it, it just seems unnecessery and bizare given that the lunars
clearly depict the moon as having a visible dark side.

BTW on the shape of the moon rune (Two rounded halves with a line down the
middle). Have I got a dirty mind, or does anyone else think this is
remeniscent of the meaning of the term 'to moon'.

I don't subscribe to the digest, but I read the archives about once a
week, so don't expect replies to posts on the digest very quickly.
