Is there a typical naming convention for Stelliferas? The only example I could find was the single NPC named Half Red.
At that point the name could be anything. You could name your stellifera Cinderella and no one short of the devs would be able to argue with you. What source are they going to cite?
As far as I know, Half-Red is the only example we have. With that, and the knowledge that their racial language is comprised of both skin colour changes and mild telepathy, you could extrapolate and brainstorm, though! Names that evoke any combination of colours, visual patterns, and probably emotions, are probably on the right track? Just spit-balling here:
"Sunset With Ease"
"White Stripe Blink"
"Sunset on the Beach" . To Land lubbers it sounds like a relaxing vacation. To a Stelliferas it denotes a warrior willing to stand on deaths door till the last second in order to ensure victory.
His older and even crazier brother sex on the other hand had their name even more garbled in translation....
