I’ve been slowly writing and adding to my campaign world setting, I only really work on this when it’s late at night or if I’m very tired. The latest piece I’ve finished up is a solar system map. I decided to start right from the top and work my way down. So I had a feel for the Planets rotational period and year length etc I worked up a Solar System Map and a few Planetary Statistics:
Above is the Original image I assembled using elements from a few different NASA photos and images that NASA have made freely available. The planets are obviously not spaced out to any kind of scale. I’ve made the Sarilo System a dual Habitable planet system, although to start with I’ll only be detailing the Planet of Etena. Once I had the above created I ran it through a few filters to try and get a tapestry effect:
It’s not perfect but it does give the impression of a tapestry, I should have really added some aging like holes and ragged edges, but as it’s supposed to be a one of kind tapestry made by a famous Astromagus. It should be well looked after and protected so aging didn’t seem very appropriate. I pulled together rough statistics for each planet:
| Name | Sihnon | Etena | Ilvaya (ilvaya) | Ceninia | Onayel | Aran | Tevasi |
| Position | 1st Planet | 2nd Planet | 3rd Planet | 4th Planet | 5th Planet | 6th Planet | 7th Planet |
| Type | Hot Gas Giant | Terrestrial (Life) | Terrestrial (Life) | Frozen/Ice | Gas Giant | Liquid Gas | Barren Rock |
| Distance from Star | 0.41 AU | 1.24 AU | 1.76 AU | 3.2 AU | 5.1AU | 8.5AU | 12 AU |
| Diameter (KM) | |||||||
| Day Length | 7.5 hours | 26 hours | 27 hours | 66 hours | 16 hours | 13.5 hours | 350 hours |
| Days a Year | 304 Sihnon Days | 465 Etena Days | 757 Hyrokkin Days | 759 Ceninia Days | 6306 Onayel Days | 16081 Aran Days | 1040 Tevasi Days |
| Equiv Earth Days | 95 | 504 | 852 | 2090 | 4204 | 9045 | 15173 |
| Moons | 0 | 2 | 5 | 1 | 16 | 8 | 0 |
| Rings | 0 | 0 | 0 | 0 | 1 | 0 | 0 |
Assuming I’ve understood it correctly I used Keplers third law to calculate Orbital timeframes and I included an equivalency back to earth days. I realize using Keplers third law wont be a 100% accurate as I’m pretty much assuming that the Sarilo System is then the same as our Solar system but I figure for a Fantasy game setting it should be fine. The other figures are all made up, I’m still working on the Planetary Diameters, need to be a little more careful with those.
As I don’t get to GM very much (or at all any more) and I really enjoy world building I’m just going to do this Campaign world building project as something fun to do when I feel like it. I will continue to add to the world and will make posts here of anything of note. I have begun to upload some of the Info to a wiki but I’m not quiet ready to post the URL as it’s very empty at this stage :).
I’ll get back to Mayhem city and Hinterland builds.
(The layout of my image above was based on this one, although mines a very poor imitation 🙂 . I believe it appeared in or on a magazine cover at some point)
