Mermaids -- *... total geek*
... I just spent about four hours running all over Wikipedia and bugging ![[livejournal.com profile]](https://www.dreamwidth.org/img/external/lj-userinfo.gif)
joisbishmyoga for the pleasure of doing that. And it's still too simplistic to give me a working calendar re: eclipses.
It's the last time I decide on a planetary system with THREE moons. Last time.
Basically, it helps me keep track of which moons can possibly rise together in the same sky and which moons just should not. For example I'm never gonna have three full moons side by side. Or a triple-eclipse. (I could have aligned them in a way that makes that possible, but then the system would collapse.)
(While the Huntress does one complete revolution around the planet, the Matron does two, and the Girl-child does four.)
... Oh hell, just look at this here animation, stolen from Wikipedia.
I think the Girl-Child -- the inner moon -- isn't actually spherical. Because she's supposed to be the most erratic one, but if she's on the inside that's getting way too complicated. And I wanted the Matron to be the biggest moon -- or to look the biggest at least -- but I'm not too sure she can do that and still be in the middle. So many things I don't know about astronomy. @__@
joisbishmyoga: Wait, no. You could arrange the orbits so that the huntress' crosses the inner moons' orbits at points where the resonance means they're out of the way. And if the orbit is also tilted the right way, the huntress moon solar eclipses would only be visible in the temperate zone where the mermaids can't live.
askerian: AUUUGH
joisbishmyoga: So you'd only get occasional lunar eclipses, when the planet blocks sunlight and the huntress moon turns red.
JoIsBishMyoga: Which would be AWESOME.
askerian: *__*
joisbishmyoga: Girl-child, matron, huntress, with the huntress tilted and the highest-lowest points of the orbit on the noon-midnight sides of the planet, and the sunset-sunrise line at the huntress' quarters. So the huntress would cross the inners' orbits when they're at full or new, a quarter-circle away from the huntress and unable to eclipse her.

joisbishmyoga: btw, if the angle's strong enough, you might never get a perfect new huntress. she'd have a thin crescent parallel to the horizon.
... And now, a map! :D damn it what's the liveable depth of the sea. auuuugh.

All three moons are the wives of the sun. The girl-child is the mentally deficient/weak-minded/smaller/submissive/youngest, brand-new wife aspect. She's not a child-child, but considering a girl can be as young as 13/14 when she leaves her pod and gets into another, and that they have no problem sexing up someone with a mental problem (as long as it doesn't make them violent or physically twists them) ...

But the cultural significance is so awesome!
I do like the chart, very much.

I'm so geeky about proper world-building. I've spent an obscene amount of time doing similar building and research. It stimulates this happy, geeky part within me. ^^

We had some wonderful cheat sheets with all the formulae for that specific test, so a .doc file should still be around... It only needs to be translated back from text-message-italian XDno subject

Should probably need more in-planet sources of conflict, it would get boring otherwise with only character-interaction type plot. Hmm. *ponders* mermaid/two-tails war! wait, two-tails are usually pacifists and what can merpeople do when they're in their islands, throw rocks? XD maybe there could be semisentient marine creatures that get a taste of merperson flesh or something. XDDDD

Uhh.... If you want pretty references to liveable sea-depths and all that I'd recommend the "Blue Planet" and "Planet Earth" Discovery channel mini-series. Both are gorgeous series with plenty of sea-life info.

Hee, thank you ^___^

Just spreading the love of those mini-series. Both are far too beautiful to hoard.

Once upon a time (shush you, my story), before there was civilazation as we know it now there were four clans in that valley that would once house Konoha.
Those Four Clans were Hyuuga, Nara, Aburame and Inuzuka. Each was dependant on the other for abilities and supplies the others had. All worshipped the The Ever Burning Flame, the Spirit of Fire, and the Spirit's Avatar, the Great Fox. (yes, I make Kyuubi nice, he has the thing for worship and having giant deer sacraficed to him, shush)
Other regions had their own seed clans, and their own gods-- The Spirit of Wind, the Spirit of Water, the Spirit of Earth and the Spirit of Lightning-- and each had their own Avatars that were appeased by worship and sacrafice. Each Avatar would chose a priest to speak for it, Kyuubi usually chose a Nara as the Nara's would actually sit quietly and listen! And they tended to lead well when the various regions went to war with the Misled Pagans of That Other God.
But the peace and tranquility of the Valley of Fire was disrupted one day by the attack of a Nine-headed Demon (the greek Hydra). The Great Fox was sleeping after prolonged battle with another Avatar, so his people had to fight for themselves. It was a hard battle, each time a head of the demon was cut off, another grew in place of it. The demon killed many people before the head of Nara came upon a plan.
Together with the heads of Hyuuga, Inuzuka and Aburame Nara attacked the demon. Aburame made his insects attack the eyes, blinding the beast. Inuzuka, together with his dogs, grappled the demon, holding it still(-er). Hyuuga and Nara took turns, slicing off a head and burning the stump until there were none left. One head stayed alive, even cut off as it was, so it and the body were buried beneath a great tree. Together, the Four Clans prayed that the Spirit of Fire would subdue the foreign demon, and the Spirit heard them and bound the clans to the valley. So now, Hyuuga, Nara, Inuzuka and Aburame can never leave, nor can they act against the people of the valley.
Too bad they forgot about their sleepy Avatar... Boy was he pissed when he woke up and found a different clan that didn't respect his divinity...

*is wrassling her own research for NaNo*
Of course, now I realize I'll have to start integrating constellations into my cultures. As if I didn't have enough to deal with with all the damn faeries. *cries*
(Still, freakin' awesome- I'd never thought anything about how having multiple moons would affect the system, at least not like this- I wonder what kind of havoc they wreak on the tides, if any? *grasps at the shinyshiny*)
[lurk]

Constellations omg I forgot about those DX
Oh man, all I know about the tides in that world is that they're hella complicated. I think they have words for every single kind of tide -- matron/girlchild influence combined, long-tide when several moons pull without letting it go down in-between, short back-and-forth-and-back tides... oh god. the language implications. @__@
Faeries you say? Heee. What's your story about? ^__^

Around new and full moon when the Sun, Moon and Earth form a line (a condition known as syzygy), the tidal forces due to the Sun reinforce those of the Moon. The tide's range is then maximum: this is called the spring tide, or just springs and is derived not from the season of spring but rather from the verb meaning "to jump" or "to leap up". When the Moon is at first quarter or third quarter, the Sun and Moon are separated by 90° when viewed from the Earth, and the forces induced by the Sun partially cancel those of the Moon. At these points in the lunar cycle, the tide's range is minimum: this is called the neap tide, or neaps. Spring tides result in high waters that are higher than average, low waters that are lower than average, slack water time that is shorter than average and stronger tidal currents than average. Neaps result in less extreme tidal conditions.
(...)
Since the orbits of the Earth about the Sun, and the Moon about the Earth, are elliptical, the amplitudes of the tides change somewhat as a result of the varying Earth–Sun and Earth–Moon distances.
Real amplitudes differ considerably, not only because of variations in ocean depth, and the obstacles to flow caused by the continents, but also because the natural period of wave propagation across the ocean is of the same order of magnitude as the rotation period: if there were no land masses, it would take about 30 hours for a long wavelength ocean surface wave to propagate along the equator halfway around the Earth
... *__*
Now I gotta figure out how long a small-moon cycle ACTUALLY IS. And what that means for the tides. And and and and omg x______________x
