What is a Sub-Breed?
Sub breeds are varieties of creatures specifically bred to create a uniform line. This is a line, with a minimum of 25 generations of creatures, that look identical to each other. Sub Breeds must also be distinctly different than and unrelated to other established Sub Breeds.
You can think of sub breeds like dog breeds. While they are all dogs, like FuzCubs are all FuzCubs, they have individual breeds which look very different from each other. FuzCubs, as well as all the other species, can also be bred to carry specific characteristics.
