Back when I first designed Enderra, I decided that it had three moons and a (thin) ring system. I did this mostly for the imagery, not really thinking about the consequences much. Multiple large moons can have severe effects on the planetary environment. Universe Today has a summary of some of the effects of adding a second, Moon-sized, moon to Earth.
The scenario they describe is extreme, and I am not quite sure where they get some of their numbers (tides “thousands of feet” in height seem off) but I am sure they know more about this stuff than I do. Anyway, even with lessened effects, I have come to think of three moons as excessive.
At the same time, I do like the “exotic” visuals. Let’s ditch one moon and the ring system.
I’ve done some math to make sure the moons don’t cause huge problems. I mostly used GURPS Space for this, since I couldn’t find formulas easily, and ran the numbers for the Moon (of Earth) through the same process – for verification. Even when the two moons align, their effect on tides should be at most twice that of Earth’s Moon. The actual tidal levels, though, depend a lot on geography and local conditions. Yes, we will have some tides that are more extreme than on Earth, but it won’t mess with the fundamental state of affairs. Nights will be a bit brighter, and there will be a little bit more volcanism on Enderra than on Earth.
Both moons are tidally locked to Enderra – that is, they always show the same face to Enderra. The White Moon’s synodic month is 30.33 days, the Red Moon’s is 43.22.
What’s in a Name?
The two moons are simply named “the Red Moon” and “the White Moon”, similar to how Earth’s moon is just called “the Moon”. I might give them name later (the three original moons had names) but I think I like the simplicity of “Red Moon” and “White Moon”.
The start of a new year is traditionally a time that motivate people to change. For some people this means an attempt to lose a bad habit, but true adventurers are in the last stage of preparation for their spring departure – to go over the next hill, across the ocean, down into the depths of subterranean realms, or into deep space, to explore the strange new lands that lie beyond.
This month’s RPG Blog Carnival is about new worlds, about their discovery and about the women, men, and other sentient humanoids who explore and colonize them. Do you run an exploration-centric campaign? Maybe a hexcrawl in a fantasy world, or about setting up a colony on an alien planet? Share your methods – what aspects do you emphasize, and how do you handle them? How do you create a sense of wonder, and maintain it? What strange lands are your characters exploring? What equipment are they using? What vehicles or other means of transportation – a wagon train, flotilla of barques, or slower-than-light Sleeper Ship? Who are your explorers, what motivates them, and who are their patrons and followers? What equipment helps them? What obstacles lie in their paths?
Share your new lands with us, if you can do so without spoiling them for your party. Show off your maps and designs. How do you approach setting up your worlds? Share your favorite world-building tips!
To participate, you simply post about the topic in any shape, way or form and post a link to your article as a comment to this introduction post. At the end of the month I’ll post a round-up with links to every post so readers have one central place to look up everything.
Stone Lake – so called because it petrifies (literally) animals.Awesome, awesome, awesome setting, as Realmwright points out. I do have some doubts about the validity of this, and even if it actually works about the details mentioned on Gizmodo, but for a fantasy / sci fi story, you can always bend reality enough to make use of it.
The City of 2050 – Nothing too original but probably worth a look if you are working on Sci Fi
Not strictly Sci Fi: Check out Project Iceworm. Seems that in the early 60s, the US Army attempted to build a huge nuclear missile launch facility under the ice of Greenland. Valuable leads if you intend on ‘building’ an under-ice colony or lair for your supervillain. Also, see the propaganda video for some impressive visuals.
Chinese Copy-Cat towns – I imagine something like this would happen if we ever explore space and colonize worlds around other stars; people will feel nostalgic for the Earth they left behind and might actually even build places that remind them of home.
The League of Legends lead designer talked a bit about player needs vs wants, a worth-while read. This is not exactly news to anybody who has even dabbled in the field, but he expresses it well – and many players do not realize these principles.
Thanks to Adam for pointing out that the downloads of Shakespeare & Dragons episodes 10 and 13 were broken. I think it happened when Google updated Docs to become Drive. Anyway, I have fixed them, now hosting them on my own server.
As a VERY SPECIAL BONUS… I noticed that I actually have a 16th episode, “The Missing Ingredient”, which I never uploaded because for some reason it also does not show up in my iTunes. It’s now been added – enjoy!
Episode 10 – Plot Part Three, Structuring Plot from Character Desires and Forces of Antagonism
Episode 13 – Setting Part Two, Creating Cultural Attributes
