That would make it Dragon Star. No I want Star People to be a suggestion option... A direction to take the campaign after you have established it as a Kerren Science Fantasy Campaign. You could go fantasy and have dragonoids from a fantasy gate arrive. Apply a plauge. Have a deluge. Do what you want to keep the campaign dramatic.
You see drama is what it is all about. The setting is dramatic. The monsters create a setting of constant physical danger. The real danger and drama in the world comes from the human conflicts. First the personal ones, between people at the ward. Then you will get into larger conflicts.. intra ward, intrawarden, political... you get the idea. However, if the conflict gets stale, you can inject a new source of drama.. star people, dragonoids, aliens from under the sea, a new plague, a plague that strikes only dragons, or any number of disasters. If the game does not have tension, if the gamet does not have the potential for change, if it has no inherent drama, then it become less interesting... potentially boring. We all know what happens to boring campaigns? That is right, They end, either mercifully (by the GM) or players begin to vote with their feet. So every campaign suppliment should always have a section on how to help build and maintain the drama of the campaign setting.
A few things I need to type about...
a) Greetings should be an arm clasp (if you are familiar with the person) or a bow, (if you don't or they are significantly your social superior).
b) A wave is always the good bye or get attention.
c) Food has an Asian Feel to it, given rice being the dominant grain. However, meat seems to be a popular food source for humans as well as dragons. We should generate some regional cuisines.
d) The funnerary customs are to burn the bodies on a high standing prye. The local scavangers would to taught the Colonists the futility of burying people.
e) Marriage is the handfasting I listed before. While it is a contract that lasts X length. If you renew once, it is assumed you will renew forever, there being a bit of shame attached to not renewing.
f) Remember that Kerren Clusters are small towns in very many ways, with large ones being 5000 people. So think small town... small airforce towns.. with new pilots flying in frequently.
g) In many ways, Feudal Japan is a good way to think of Kerren. There co-op economic systems, their elite fighters, a lord that rules over most aspects of life in their domain/ ward, and an honor system (more chivalric than bushido), all have echos to Feudal Nippon . However, the change of honor code and the loyalty projected to the Ward, rather than the Lord/ Warden, make all the difference.
h) Clothing:
Male: Breeches and shirts. An over jacket for nicer occasions.
Most of the men's shirts are of the Cavalry or Russian cut, so the buttons go up the side and across the top of the chest.
Female: working- Breeches and a variety of tops
: less active working or off work, skirts, with a variety of tops.
Single piece or nice dresses for nicer occasions. Souther women tend to wear them all the time.
Boots are the normal wear. They range from low to thigh high, cuffed and non cuffed. The bugs in Kerren make flats/ slippers for anything other than inside very impractical. (heck even then...) . Short people wear higher heels, male or female both.
Ryders wear breeches and shirts. Sometime the pants are leather. They almost always wear a leather jacket, again with the Cavalry cut. Many of their jackets and some of their pants are hard leather or with hard leather patches. This allows it to function as Armor against Zhan. Some people wear an aviator's cap, of soft leather or hard. They will frequently have goggles and their wing scarves. They wear heeled boots as well, to help with their stirrups. When not on duty, they will wear more normal clothing, but often throw parts of their Ryding uniform in to show off their status.
The rain gear of choice is a duster, perferably of oiled cloth or soft leather. Herders tend to wear a distinctive hat (cowboy).
Umbrellas are seen in fair and foul weather, for shade and protection.
Fans are common for women and men in the South, but only for women in other areas.
