The smogpunk land of goblins in the World of the Everflow was set apart from the Kingdom of Sheljar, Crinth, and other areas for a few millennia. Within this separation the goblins and hobgoblins changed from the standard tropes.
In the Everflow they answer to the Queen Mother. Everyone is organized around their family’s history of developing teknology for one of the various guilds. Inventiveness and cleverness are more important than fighting and viciousness.
To emphasize these differences, but still capture traditional goblinoid feelings there should be a some differences in language. This discovery of numerals from the 13th century feels proper for the gobkon of the world.
It works in a printing press, scribbled on paper or carved into wood.
Will it ever see the table? Probably not. Or maybe just one or two numbers in a handout for the players to demonstrate the differences between their lands with the languages of Telse (Common) and the rest of the Six Kingdoms.
If there was a campaign book for the World of the Everflow this could be a tiny sidebar for flavor, not a rule for use.
