On the orbe the two moons seems to have the same orbit, one smaller before a bigger, so we can expect that the smaller appears before the night and the last one is like our owns.
But in the picture, moons seems have a consistent size. I should definitevally read this article. Any astrophysician on the place ? =)

Re: Songs of the night sky
Brightness isn't an issue. If the reflectivity (albedo) of the moons is lower than ours and they are at 90-100 degrees to each other it would be rare that there were bright nights (ie nights that are brighter than ours).
Also tides are influenced by gravitational pull. Massive tides would not automatically happen, 2 moons with a total mass similar to ours would not create significantly larger tides than what we experience but it would set up a strange tidal pattern. Eg Main high, little low, main low, little high.. The little tides would be like a dip or crest in the middle of our current tide pattern.
That said 1 moon is easier to grok until humans live on other planets with 2 moons to get effective first hand data.

Re: Songs of the night sky
I'm currently playing with the idea of two moons, one white and the other black-grey. How I'm running it is that the two moons follow an opposing elliptic, also eccentric, pattern to the one that the earth travels around the sun. This means that they shift from circles to a more oblong egg shape and back over hundreds if not thousands of years. My reasoning for this allows for them over time to eventually align, nothing big is going to happen at this point... completely not. Not like they align perfectly and cause an eclipse... Nope... But aside from that, giving them opposing elliptic pathways means that only one moon will ever be close enough to the earth to provide a large gravitational pull. Of course the odd occasion that they align, either farther from the planet or closer, would be similar to our spring tides but far more catastrophic.
Now, I am also interested in constellations, I can’t remember if there is a section on the stars or anything similar, but what types of constellations are other GL’s playing around with?

Re: Songs of the night sky
Nothing is writing about. But maybe some could be easy to create :
For my curiosity, what are the name of your two moons ?

- The Caernide
- The Bear
- The Calyre
- The Wolf
- The Oak
- The Fish
- The axe
- The barrel

Re: Songs of the night sky
And don't forget about the differences there could be between the traditional constellations and the Temple's!
Allez, come on, allons-y, here we go, en avant, godspeed, hardi, let's do this!
Re: Songs of the night sky
Thank you Iz I'll go wild making a star chart sometime later this week or next week.
Clovis, you raise a good point. I'll definitely take that into interpretation and I might just make two star charts, maybe even three depending on my free time.
I've named my white moon 'Willow' and the Black-Grey 'Thorn'.
Reasons for their naming:
Willow - The white moon pushes and pulls unnoticed as the seasons go. The White Moon is a source of clarity, reflection, and peace. The moon is viewed as a patient and wise old spirit, like a Willow Tree.
Thorn - The black moon does not push and pull subtly, by itself the moon cannot affect the tides and the world greatly but in conjunction with Willow, the white moon, it can lay waste to the land with their combined gravitational pull. Stormy and dark, those that are superstitious will not go out even during the day of a Thornmoon Night for fear that they will not be safe. Thorn is viewed as a source of dread and under certain astrological signs birth beneath a Thornmoon Night is a fate worse than death.

Re: Songs of the night sky
Wow, this is going pretty far, isn't it? Not that I'm disapproving; it's impressive to see how interested and dedicated everyone is about this!
Your descriptions of the two moons raise another question on my part: how learned would you consider Tri-Kazelians to be in astronomy? Obviously, for most people, it will just be a big sphere floating high above in the sky, but how about professional astronomers (there is an "Astronomy" Discipline in Erudition after all), Magientists, and Demorthèn? How advanced could their knowledge of phenomena related to celestial bodies be according to you?

Re: Songs of the night sky
The average run of the mill Tri-Kazelian would not have a grasp on what they moons are, just superstitions tied to them.
Usually in any campaign, in any system, I include an astronomer at some point who is attempting to calculate the distance between the moon and the earth. (Anyone who can guess the series of fantasy books this is referencing gets my applause.)
As a whole most astronomers would still have portions of astrology mixed up in their view of the night sky. While they may understand that the moons are in fact actually physical objects floating far away it is unlikely they would actually understand what effect they have on the world.
A Magientist on the other hand with an interest in astronomy would most likely understand more, and perhaps would have taken note of lunar events over the years.
Demorthèn from my perspective would know a great deal more about their affect on the world. This also comes though from the fact that in my rendition of the setting I've made the moons more prominent in Demorthèn tradition, I'll also be including basic astronomy, particularly navigation by the stars, in the teachings of any player that chooses to be an Ionnthén.
But this is just my take on it, you guys don’t need to follow it.

Re: Songs of the night sky
Well it's ok for me. Just for the navigation with stars. I prefer thinking that there is no fixed star on the night sky (elliptic orbit of the Esteren planet ? => explanation of the warmer and colder period of 400 years).
