If you click on the link, it becomes readily apparent what the problem is....ExerciseRead this article and then figure out: how many moons does your world have? How long is a month for each of them? What are they named? Do you have any scenes already plotted in which moonlight is absolutely necessary? If so, be sure to write down the phase of the moon you need on that date, and use that date as your "touchstone" for what phase the moon will be in on other days. If you need to, write out the moon's calendar and as scenes happen when you write them in November, jot them into your calendar so you know what kind of moon your folks might encounter at those times.
Yeah, so I can't read the article, but I can sort of extrapolate the intent and work on the questions from a static standpoint. And again I find myself with the problem of creating multiple worlds and having multiple places to put moons.
It does bring to mind something I do try and do whenever I write up planetary details; I do try to take satellites into consideration. Moons around a planet do offer illumination at night, or cover when approaching a world. It presents new and interesting locations for the adventure to take place in. Finally, the moon itself might be the habitable stellar body within a system, and in which case it's relationship to the planet could be important. A satellite might not have much of a dark sky at night time if the gas giant it orbits around is reflecting all that light onto the world. Similarly, when the moon is in the planet's shadow, the whole moon is dark, and gets REAL dark too.
What kind of living facilities are necessary to live on a moon? Some barren moons may need a full enclosed base, as we would need on our moon. Some may not need such facilities, if they could be terraformed or were habitable from the start.
One of the races will come from a moon in one of the systems, originally. Likely they will have colonized their system and possibly moved on to nearby systems as well.
Another day where a little more detail gets presented. I've started to go through my exercises from the month and added them to the Obsidian Portal page for the campaign. It's really neat to see the pages practically fill themselves out. A lot of it is just bullet points at this stage, but that's okay; it gives me something to work on and compiles it all in one location.
I'll be working on that, and a couple other things as we count down the days until the end of the month and the completion of this step of the project.
