Wyrm = only wings Wyvern = legs and wings Drake = smaller less powerful dragon Dragon = OP AF legs forelegs and wings.
Generally everything but a wyrm has breath attacks but wyrms can have them if they are a high tier wyrm.
I truly like your story, but these mistakes are so frequent, that its nearly unreadable.
I hope, that the story gets edited, but until then i'm off
