I have a few.
Caerulium: a blue, non reactive metal with a similar cultural role to yinrih as gold has for humans. Claravian sacred objects such as thruibles and aspergillia are often made of caerulium. The Commonthroat word for caerulium is rdfsjHg, which means “sky-metal”
Tailstone: a magenta-colored crystal that’s used for FTL communication. Partisan Territory is the largest supplier of tailstone to the rest of Focus. The word tailstone is a somewhat inexact translation of the Commonthroat sKGqrCg, which uses the word rC meaning to flick with the tail. To flick oneself on the side with the tip of the tail, as though shoeing a bothersome insect, is similar to a human dismissively waving the hand.
Polymerite: A material that can be molded or extruded like plastic. After being cured through exposure to gamma rays, it becomes as strong as steel. Polymerite comes in a number of grades, all of which are naturally neon-colored and translucent. This gives a lot of yinrih tech a distinct late 90s aesthetic.
Floatstone: This one’s fictional in-universe. It’s a substance said to be able to negate the effects of gravity. Many yinrih choose to live permanently in orbital colonies without any artificial gravity in order to free up all four paws for grasping and manipulation. Many dream of having the convenience of living planetside with the freedom of movement afforded by microgravity.
I thought adamantium was public domain? I feel like I’ve seen it used elsewhere.
It may be, I’ve not checked.
But it’s still not something I’d risk without full verification, and I wouldn’t really want to use it in my writing tbh. It’s already been chewed gum.
There’s not really any truly new ideas at this point, but directly lifting someone else’s creation defeats the purpose of writing for me.
