Mystaran Astrology: Moon charts

by Patrick Sullivan

I'm going to be working up natal charts for the characters in my current Vilaverdan campaign, since Savage Baronies provides the tidbit that Vilaverdans love fortune-tellers and divination. I want to go a bit beyond what's available in the Almanacs, so I've sketched out a system for determining a character's moon sign--where in the ecliptic Matera was when the character was born. I'd like to solicit feedback, and I figure this might be useful to others, too.

I started by assuming that Matera orbits Mystara 13 times each year. The alternative--11 times per year--would work, too, but would mean that its motion through the celestial sphere is opposite that of earth's Moon. I can't think of any particular source that details whether Matera's movements correspond or differ from Luna's: can anyone else think of anything?

For the casting, I plan to interpret a moon-sign as kind of a negating influence. That is, someone with a particular moon sign lacks the characteristics of that sign, to some extent. For example, Since a Giant is selfish, strong, and stubborn... someone born with Matera in the Giant tends to be selfless, weak, and agreeable. These negating tendencies are less strong than the solar sign. A special case are those born at the beginning or end of each month, when Matera is in the same constellation as the sun: in this case, the sign is moderated to some extent, and the influence of the nearest other sign bleeds through--the character is born on the cusp of the two signs, although the solar sign is still the primary influence.

I'd love feedback on 1) the astronomical accuracy (I think this is all accurate, based on the 13-orbit hypothesis), 2) the astrological accuracy (I'm not an astrologer by any means! Alternate interpretations are more than welcome!), and 3) whether any other Mystara products have insights that I've missed.

The chart shows the time and day when Matera enters a particular constellation. The times should be accurate only at a particular longitude--the Sundsvall Meridian, perhaps--but I don't think I'll try to figure out time zone differences.
