Drachynfolk Physiology study I drew up.
Kind of simple and a bit ass but I tried.
A couple addendum notes:
1) Lesser Dragon(esse)s don't start off with that body shape. It develops as they mature. They start life, similar in shape to a common Drachyn, but still have their unique snout shape.
2) Vrastelians developed their mammalian features due to the habitat their forebears grew up in. Extra protection from the cold, plus heightened senses allowed for all manner of predation, instead of the simple sight-based ambush hunting of the forebears of other breeds.
3) Yes, the Echsevuld are basically kobolds.
