Additional Civilization Tokens:
Basically this token will enable a race to have markings or tattoos designated in the typical images of their society (it would use the same code that engraving or any image setting would use for the race). This would add another aesthetic layer to descriptions of a creature or sentient, allowing you to tell all kinds of history related to it. Maybe this creature was in an epic battle and he has markings to commemorate it? Maybe that Orc has an image of his wife drawn onto his sleeve? Maybe that dwarf got drunk one night and made a bad decision to get Goat Cheese engraved across his back?
Then there are subtypes, which basically just determine how the marking is made, tattoos are inked onto the creature, markings are carved in (ouch), Paints are just simply painted on.
As it currently stands, this idea would apply to worldgen and other civilizations and not the player's playable civilizations. Only migrants and the starting dwarves would have randomly attributed markings until a suitable way for dwarves to get markings could be created (and not a complex industry, moreso like "if they're bored they might get a tattoo from a friend").
