I remember seeing this image that explained all the stages of like goblin/human children through the years, with art showing female goblins slowly becoming more humans as the bloodline would thin as more human traits are added, the different stages having different human/goblin traits and how they were seen in the society.

I can't fully remember it but it had around 8 stages and had descriptions of each that was like:
>"Quartermaidens" are 25% goblin, 75% human but still retain goblin traits such as pointy ears and are below average height. Society view them lower than humans but some places accept them.

Any help would be appreciated, thanks.
