The World of Calidar as presented in the first book, "In Stranger Skies", depicts a star system somewhat similar to our Solar System. The sun is called Soltan. The heroes' planet is Calidar, which possesses three moons, two orbiting on the same path (Alorea and Kragdûr), on opposite sides of Calidar, and the third further out (Manaan).
Two other planets exist nearby—Draconia, closest to Soltan, and a red world, Lao Kwei. The latter has a moon called Kumoshima. Based on their names, I’m sure you can figure out the general nature of these settings. Beyond Lao Kwei lies the Fringe, a ring shaped collection of dwarf planets and asteroids. It is a cosmic frontier with all sorts of hidden worlds gravitating alone or in clusters. An extra planet, Ghüle, also orbits through the Soltan Ephemeris. My previous post describes this most peculiar world.
Having listed these asters, the issue of travel time quickly comes up in a world where space-faring skyships are the norm. I’ll skip the "how" because this is a chapter of its own which will be featured in the upcoming book. This preview provides a few other things, such as the illustrations above and below and a calculator to plot the positions of planets based on a calendar date. I decided to tackle this topic since the Star Phoenix’s story lists dated log entries, which means I can’t just "fudge" travel times.
The diagram above shows the approximate orbits of planets. The diagram on the left shows the relative sizes of the worlds. The hex grid helps estimate travel times. Using the various magical techniques available in that universe, the fastest travel speed between planets amounts to five days per hex. From a mother world to a nearby moon takes approximately 15 hours, or in the case of Manaan 20 hours.Two other planets exist nearby—Draconia, closest to Soltan, and a red world, Lao Kwei.

Several points are marked on the first diagram, as follows:
B: Ghülean orcs may begin raiding if Lao Kwei is in range
C: Ghülean orcs may begin raiding if Calidar is in range
D: Window of opportunity to raid Calidar ends
E: Window of opportunity to raid Lao Kwei ends, however the Fringe is now within raiding range
F: Window of opportunity to raid the Fringe ends
G: Ghüle has frozen over and will remain locked beneath ice for the remainder of its orbit
Because of the difference in orbital speeds, Ghüle’s raiding season on Lao Kwei can only last at most 24 days. Raiding season for Calidar can last, however, as much as 45 days!
The trick is that planets move while skyships travel. Likewise, the actual position of a world on its orbit path at a given date makes a huge difference. I posted a calculator to help figure out where planets are. It is located at the end of this article because of formatting issues I've been unable to solve. All you need to do is enter an actual date. The calculator is set up with the 3rd of Loreath 1512 (the fall equinox in Calidar’s northern hemisphere) as its default "start date." Entering a different date will show where the planets move to. Positions are expressed in hours and minutes, as if Soltan were the center of a clock, twelve o’clock being "north" on the diagram, six o’clock "south." This provides a quick and simple way to locate the planets and measure the distances between them.
