Drake, in reference to dragon kind, is most literally, and originally, by all references an obsolete word for dragon. This is of course understandable given that dragon comes from the greek drakon. The nature of drakes seems to be a matter of contention, the two primary reputed forms and positions are at times totally contradictory.

Drake n.

1. A greater dragon, or ancestral dragon, possessing no wings, four legs, and a long body. A fire drake. Elemental dragon. (traditional?)
2. A lesser dragon, a smaller version of a classical dragon, baring a resemblance to a winged crocodile, often in a transitional form towards a wyvern. (modern popular)
