Ancestors
Sea Serpents
Sea serpents are the dragons earliest ancestors. The ancient sea serpents came onto land and eventually went on to create proto-dragons. Sea serpents are long and have six fins that went on to become limbs. They live in the water and can go very deep. Many do not need air, but some species still have lungs and live in shallow waters.
Proto-Dragons
These are dragons before dragons. They looked very similar, but lacked the magic sacks that new dragons have. This species then split into true dragons, and fake dragons. Fake dragons tend to look more like birds, and do not have magic sacks.
