What is considered fiction?

[Sovereign]

I find that curious.

Why rename stars like that? I'd go with Alpha Centauri, Beta Centauri...

Or I'd go with Centarus or something.

Just read the time line. Quite impressive. I like the way you described the fall of old factions and introduced new factions. Look forward to see more details.

Thanks for your comments HongHu!

Nessus is definitely a moon, as said by Nessus Mining Station, or something like that. I think it was one of the orbital things you build to increase base production.

Is there only one moon orbiting Chiron?

[GeneralTacticus]

There's definitely more than one... either two or three, I don't recall which.

[Sovereign]

Actually it depends.

In the game start-up menu, IIRC, when you set Erosion, you pick light, moderate, and heavy.

With light, you get 1 moon, moderate with 2 moons, and heavy with 3 moons.

Least thats what I can remember.

But officially, I know there's at least one. It's Nessus. Dunno if there's any more "official" moons.

[Illuminatus]

Nessus, Pholus ( I do not think that third one had a name).

[Sovereign]

Pholus? I thought it was Pholus Ridge and Pholus Mutagen?

[Illuminatus]

They were called by that moon.

[Mr. President]

You'd think the Pholus Ridge would have to be on Pholus. Apparently not.

Like the Nessus Canyon (which I'm planning on renaming anyway; I guess I'll have to rename the Ridge and the Mutagen to the Deianira Ridge and the Deianira Mutagen too).

[Sovereign]

Where is it stated as canon that Pholus is Chiron's 2nd moon?

Well it is obviously named after Pholus, just like the Moon River would not be on the moon.

A quick 'gazeteer' of some of the geography of Chiron in PY50

I still don't have my computer yet (I'm using the pesky university network right now...) so I can't make an actual SMAC/X map, but I have worked out on paper where things are likely to go and what they will be called.

Chiron; Planetary Year 50.
The planet Chiron contains two major continents, and several smaller islands.

The first continent surveyed by the Unity's probes was Chariclo, named for the mythological Chiron's nymph wife. Chariclo is shaped roughly like a crescent facing towards the east and is dominated by the Chironian Alps, a massive rocky spine the rises steeply out of sea. The mountain range seperates the continent into roughly three sections: the Coastal Plains in the south, where a river spills down out of the Asbolus Canyon (formerly: Nessus Canyon) and towards the sea; the Red Valley in the north, where a river passes through highly radioactive red-dust plains creating the Bitter Delta (formerly: Uranium Flats); and finally the the so-called Promised Land, an alpine plateau in the western centre of the continent that was named by the Believers who settled there first. At the centre of the mountain range lies Mount Pelion(formerly: Mount Planet), the home of the mythological Chiron. Mount Pelion looms over the Chironian Alps and the bubbling Sea of Steam (formerly: Geothermal Shallows).

The second continent surveyed was Ocyrhoe, named for the daughter of Chiron and Chariclo. Ocyrhoe is roughly oval in shape with a thick spur jutting out towards the north-east that broadens into a wide plain. This region is known as the Monumental Plains (formerly: The Ruins, but altered into an avenue instead of a square) and possesses a great number curious alien structures. The most peculiar and useful of these are The Gorgons (formerly: The Borehole Cluster), three vast fissures that penetrate right down into the burning heart of Chiron's mantle. The Sentinel Ranges lie at the end of the north-eastern spur and rise very close to the north-western coast of Chariclo, creating a narrow channel named The Pillars. The centre of Ocyrhoe was named the Valley of Eden by the Gaian settlers and consists of a lush native jungle (formerly: The Equatorial Jungle). The Valley is protected to the north by the chill waters of Northern Reach where it is said that the shattered remains of the Unity lie (formerly: Unity Wreckage, but with most benefits disabled) and on the remaining three sides by mountains: to the east, the Central Highlands seperate the Valley from the Monumental Plains; to the south rocky highlands give way to the sun-drenched Southern Plateau (formerly: The Sunny Mesa); and to the west the
Garland Range plunges down into the fertile basin of the Riverlands, this verdant expanse is marred only in the north by the Garland Crater, where one of the colony modules crashed into the surface.

The two continents are connected by range of seamounts that almost breaks the surface halfway between the two landmasses. At this point a curious Fossil Ridge (suprise: The Fossil Ridge) can be observed by those with the skill to negotiate the colliding currents of the Open Sea to the north and the Southern Reach to the south.

Far to the north of the Open Sea lies the large island of Deianira named for the wife of Heracles. Its main feature is the steep ridge that runs east-west along its entire length, the Lichas Ridge (formerly: Pholus Ridge). To the west of Deianira, and to the north of Chariclo lies the vast dark mass known as the New Sargasso, a huge floating colony of native plant and animal life.

The currents of the New Sargasso spill down through the Pillars and into the Sea of Nereids (formerly: Freshwater Sea). Three small islands mark the boundary between the Sea of Nereids and the larger, more bitter, Closed Sea. These islands Arethusa, Galatea, and Psamathe are each named for nereids and each have a small alien pillar on them, although the significance of these monuments is still unknown.

Along the eastern edge of the Closed Sea, barely seperated from the south-west of Chariclo by the foaming waters of the Roaring Gap stands the island of Tiresias. This steep island, named for the son of Chariclo who became the famous blind prophet, is the location of the so-called Alien Temple ([i]formerly: The Manifold Nexus) which the University Enclave continues to study for its archaeological secrets. To the east of Tiresias lies the Grey Sea a frigid body of water full of ice-crystals and churned its signature colour by the violent current spilling out of the Roaring Gap.

The various new names for landmarks should be explained in the text, but if anyone has any comments, please post them!
