| Moons || Most humanoid civilizations in and around The North use lunisolar calendars to keep track of months and seasons. A single large, silvery-blue moon shares the night skies with a host of constellations; aside from its size and color, the moon here is pretty much the same as the one orbiting Earth. The lunisolar calendar is arranged to start with the autumnal equinox, during Harvest Moon (which roughly coincides with the Gregorian calendar's September), and proceed through the Hunter's Moon, Silver Moon, Cold Moon, Wolf Moon, Snow Moon, Sap Moon, Rabbit Moon, Blue Moon, Bear Moon, Honey Moon, Elk Moon, and Trout Moon. Occassionally the autumnal equinox falls before Harvest Moon. In those cases the month is named after the local dominant god (in the North, it is usually called Sylena's Moon). During a new moon--when only the dark side is showing--one month rolls into the next. Clergymen and astrologers are trusted to keep an accurate record of when this occurs, but neighbors are often one day ahead of or behind one another in their estimates of the date.
| Centuries || Just as days are measured in terms of months, or moons, so are years measured in terms of centuries. Astrologers name each century based on the dominant constellation on the first night of the new century. The hundredth year of a century is never referred to as the hundredth year, but instead the "last" year. In the current campaign, the century of the Tempest has only recently begun and the aptly named century of the Serpent has just ended. Because of the apparent foretelling in the naming of the last century, many people now believe that the coming century will have many storms, or will see storms real and imagined wherever they look and then apply it to the name of the century. The various clergies and learned men and women of the North refer to this superstitious fortune-telling as "astrology", and are generally quite disapproving of it.
