I had originally wanted to put my system in Epsilon Eridani. But that was soon discarded. The system isn't right, and far too close to Earth for my purposes. E.Eri might show up as a setting for some important scene or the other, or just be discarded. What I ended up with was Beta Hydri, a type G2 VI star some 24.33 light years to our Galactic south. A very old system, with on;y 500 million years left before expansion and death, but time enough for humans. It's much brighter than our Sun, and as I generated it, has eleven planets.
The first three are airless, tidally-locked rocks all within 1 AU of the star. They are named Mongoz, Kobara, and Chooha (Mongoose, Cobra, and Rat.) There is occasional mining and scientific operations, but the tiny worlds are pretty useless. Moving out, all the worlds except the main world of the system are named for heroes from India's fight for independence from Great Britain. Lakshimbai is a sub-Jovian world with a small family of moons, and is the headquarters of the Hydran Navy's operational arm.
Naya Ghar (New Home) is home to the bulk of the system's 7.9 billion residents. Slightly smaller than Earth, with .77g of gravity and an atmosphere 1/5th as dense as ours, the surface is nearly half water, with the planet carved into a series of landmasses separated by channels and small seas. There is life, mainly in the oceans. Land forms are mainly plants and smaller animals. There is considerable evidence that the world once had a thick atmosphere for a long period.
Cities are a combination of underground warrens and sprawling surface facilities. Going outside on a summer's day requires a respirator and emergency oxygen supply. The days are 18 hours long, a year is 2.13 standard years. or 1,037.6 local days. Older cities tend to be named for Indian cities on Earth, while newer settlements are named for local terrain features.
Naya Ghar has two moons, both of which are in fairly distant orbits. Their tidal forces are relatively weak, with the exception of those times when their orbits cause them to exert a tidal pull on one side of the planet. "Flood days" are a well-known phenomenon and are seen as part of life on the shores of the many waterways.
There is an ongoing effort to terraform Naya Ghar. Working with the powerful firm Planetary Development Incorporated efforts have begun to thicken the atmosphere in hopes of reaching double the current pressure with an oxygen level that would allow people to walk outside freely. Critics point out the amazing diversity of life already on the planet and the probability of this life being destroyed.
Next out, at 2.78 AU, is Khan, a small Mars-like world wracked by near constantly dust storms. Virtually worthless, it has become home to a colony of Punjabi Sikhs who tired of the Hindu majority on Naya Ghar. Despite near poverty, the colony has become something of a tourist destination and the Hydran military has a strong Sikh component.
The next four worlds are all large gas giants, all with smaller than normal sets of satellites. Chandrasekhar, Bismil, Lahiri, and Bhagat all support vibrant Helium-3 scooping and refining operations. The system's hyper-limit as at 11.04 AU, between the orbits of Bismil and Lahari.
Finally, the is frozen Bahdur, 41.4 AU from the sun. A sub-Jovian, Bahdur has been judged as too distant for economically feasible scooping operations. It has become the main training ground for the Imperial Hydran Navy due to, in the words of one Admiral "It has plenty of worthless rocks to blast into worthless gravel." The planet and it's immediate surrounds are marked as off-limits to unauthorized vessels.
The central star, Beta Hydri, is either called Hydri or just Ravi (Hindi for "Sun") by the residents. As most of the population lives in sealed cities and rarely see the sky anyway, the name doesn't matter to them much anyway.
The system's population is primarily from the Indian subcontinent. After the spasms of the mid-21st century and the Warpox plague, reducing the excess population of India became vital. Later waves of immigrants came from North America and Central Asia. Hindi and English are the languages most spoken, with Hindi being the official language of the state.
Tomorrow, the Great Hydran Empire! Or the Mahaan Haidraan Saamraajy (The Raj, to most people.)
