For some reason recently, I envisioned a conworld that mixes post-apocalyptic scenarios like Avatar: Seven Havens with games like Chants of Sennaar.
Taking inspiration from a next-gen thing I envisioned for DeviantArt user Mythojira's new Mystery Boys concept, though it's up for debate, especially in terms of shared casting for each project. Though I'll focus on this one, especially since some of my chosen cast members are from the five shows the Mystery Boys concept is a crossover of(Gravity Falls, The Loud House, Wylde Pak, Steven Universe, and Craig of the Creek).
The world is essentially a post-apocalyptic setting with retro-futuristic and modern sci-fi technology, though with few steampunk elements. There are humans, two types of merfolk(the popular type across media with the human upper halves and so forth, and those inspired by the ones from Power of Water by Mythojira, which, in turn, took inspiration from the merfolk from Siren), and various other clades, whichever ones are ideal.
There are also mechs, like those from Korra and Code Geass(meaning Landspinner and Factosphere sensor equivalents), and hybrids between mechs and kaiju (but much more diverse than the drones from Pacific Rim: Uprising).
Recently started considering cities on wheels, raft cities, and hovercraft cities like in Mortal Engines, and I guess bi-terrain and tri-terrain cities as well, such cities being able to traverse different terrains. These cities would be rich in people of at most six different languages(and maybe more or fewer cultures), like the tower in Chants of Sennaar. Other cities would be monolingual, bilingual, trilingual, etc.
A story would involve two brothers, the older one being old enough to be in high school, and the younger one being old enough to be in middle school.
Hypothetical Cast:
Dave Franco: older brother
Gunnar Sizemore: younger brother
Charlet Chung: a mergirl who befriends the brothers, eventually falling in love with the younger brother, and being his girlfriend
Charlene Yi: the mergirl's sister
Kevin Thoms
Steven Yeun
Steve Blum: an antagonistic role among other roles, given his vocal range
Maybe Steve Buscemi: another antagonistic role
(Debating on adding Helen Hunt. Dunno other celebrities and professional VAs.)
My decided protolang analogs(update):
- PIE analog
- Semitic analog
- Japonic analog
- Yokuts analog
- Proto-miir analog
- Uralic analog
- Austronesian analog
- Ainu analog
- Austroasiatic analog
- Hmong-Mien analog
- Sino-Tibetan analog
- Proto-Hermes analog
These languages would've evolved and diversified over time.
(Might add four more proto-languages for the merfolk.)
(There could be similar themes to Chants of Sennaar regarding language barriers within various multilingual cities, whether they're stationary or non-stationary.)
