bad wording i suppose. I know they CAN fly and CAN land. I want to know if there are Drakes. Dragons that are not capable of flight because of a lack of wings. Or if there are dragons without limbs like seen in some mythology. I want to know about their configuration. Not how to fight them. Sorry for my lack of clarity.
Every time we've seen a dragon in the flesh they've been configured exactly the same way. Two wings, no arms or forelegs, two legs.
Peryite is depicted as a creature with two wings, two arms, two legs, and a very long serpentine body and with serpentine head, but we've never seen whatever the hell kind of creature that is in any of the games. So we can't say that whatever form Peryite takes is any form of creature known to inhabit Tamriel.
