World-Building... in Space

For this update on my world-building activities, I will be detailing some aspects of the world of New Fiction Idea #17 (not Macbay Transportation Services this time).

Tevyne

Tevyne is the home planet of Liutas. Our lion-man is of the planet's dominant species. Due to the general environment, most groups are nomadic. There is a long history of warring tribes/clans, and the society is collective and honour-based. By the advent of the Human Empire (which, incidentally, branched off from Earth's "lost" colony and doesn't actually involve Earth), most of the planet's technological level was similar to ours today. By now they've caught up to the rest of the Empire and usually work with the military (although only if they're accepted with the rest of their family or friend group).

Salynas

Salynas is the home planet of Kaliause. It is mainly water, with most land masses being archipelagos. As a result, many different genotypes, cultures, and languages are isolated; they adopted English as a planetary language because the Human Empire found them before any native language spread significantly. Around Kaliause's part of town, the culture is individualist, although family units are a very close second in importance culturally. The language is primarily based on a musical scale, but different vocalisations with the same "tune" have started to come up, especially in slang. They were at about medieval-era technology before the Empire found them, and they've (some archipelagos more than others, mind you) pretty much caught up with the high technology of the time.

Domus

Domus is the home planet of Stannum. First colonised by humans, it has been terraformed and contains a mostly human population, although some smaller, "uninhabitable" areas have been taken up by other intelligent species, and some species more physiologically compatible with Earth conditions live in the cities. As such, it's very similar to Earth of the same time period, plus the extra diversity. Stannum was once an average businessman with a small household he didn't particularly like, but he died of heart-related issues. As is common in highly-populated areas in the same galaxy as Valka, his body was kidnapped and "reclaimed" to work endlessly in the haunted graves.

Valka

Valka is the main setting of the story. It's been war-torn for some time due to outsiders trying to secure its natural resources (by blowing a lot of it up, but let's not question the ones with the guns...). Even before battles started breaking out, it wasn't a particularly pleasant place. Some sale of resources has led to a very corrupted upper class and government, and its cities are nearly entirely underbelly. Its original dominant species was pterodactyl-like, but it hosts a large diversity now.

This is a very vague summary, but let me know if there's anything in particular you'd like to hear. I'm still in the process of fleshing these places out a bit, so I'll be glad for an appropriate challenge.
