# E2015: The Moons of Enderra

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”.

# E2015: Revisiting Enderra

Oh, Enderra. You were my first fantasy world. I named this site after you. And yet, I have neglected you for a decade. I am sorry.

I’ve recently been in the mood to do some fantasy world-building again. Part of it is that I’d really like to get back into gaming; part of it is a desire to get rid of all those post-Enderran attempts at fantasy worlds that are cluttering my Worldbuilding folder. And part of it is that I’ve been doing too much Science Fiction in the past few years.

And there’s another reason. My nephew is going to be old enough to start gaming in a few years. I should prepare for that.

Enderra is now over twenty years old. It was created, more or less ad-hoc, for a GURPS Fantasy campaign, but it’s been used with my own D&D clone rules, Tunnels and Trolls, AD&D 2nd, D&D 3rd, and even TORG. We played campaigns of our own invention and “official” modules. The Temple of Elemental Evil, to me, is not in Greyhawk – it’s in Eastern Enderra.

Enderra already went through one major revision, in circa 1999 when we started our D&D campaign. I had not been happy with some of the decisions I had originally made, so I advanced the timeline and changed a lot of stuff around.

So – what are my goals for Enderra 2015?

Since Enderra is not actively used by anybody, and I have published very little of my material, I feel like I can afford to reshape the setting from the ground up – apply everything I have learned about world-building in the past twenty years. One of the lessons I learned is that it really helps to have design goals and guidelines:

1. Enderra Is Real: Well, it’s of course not really real; but the approach should always be that “this is not a game” – Enderra is a parallel earth, and can easily be found in a universe one phase shift away from our own, if you just know how. I believe that treating it as “real” will help make the right design decisions.
2. Enderra must be internally consistent: This is really my number one golden rule for worldbuilding. Everything must make sense inside the setting. If there’s a Raise Dead spell, then why isn’t the world ruled by immortal kings? Or is it? Hmmm!
3. Enderra shall not be a kitchen sink. Do you remember Eberron? “If it exists in D&D, it exists in Eberron”. Or consider RIFTS. Kitchen sink settings rarely work out well.
4. Enderra is not a hexcrawl: Hexcrawls might be compelling, but a world consists of more than random hexes filled with combat encounters. Enderra is a place, its inhabitants lead lives, plot against each other, wage wars… I’ll use the story-based approach described by Paul in the Shakespeare & Dragons Podcast.
5. There are no holy cows: I’ve got a lot of material and notes about Enderra. I have even more in my head. I will re-use material where I can, but if there’s a better way to do something then I will change it.
6. Enderra shall be a fantasy setting that works with D&D and its clones.  This doesn’t mean that much, considering how archetypical D&D really is. It does imply certain assumptions, for example how magic works, and will guide certain thematic or stylistic choices.
7. Enderra must be compatible with Contact Light: Enderra is the “lost homeworld” of the Contact Light setting. This places some minor restrictions on my design – for example, I can’t turn Enderra into a Ringworld.
8. Produce a publishable World Book: By publishable I don’t mean “for sale”, but my end product should be a campaign guide that other people can use. This places some limitations on the scope of the work, and above all, provides me with a measurable goal.

Let’s get cracking.
