The creature has the head of a dragon, and its forked tongue, scaly neck and leathery wings, but combines with these the two clawed feet of an eagle.
Hissssssssssss!!
A deep sound which sounds like a hot sword plunged into water, and a low, deep-throated growl, much like that of a bull escaped from it's mouth as it chased after Williams relentlessly.
"Damn it! I didn't offend you, nor did I take what is yours. What is your problem you monster" Williams legs skided against the hard ground as he made a halt. He turned back and stood his ground as the wyvern approached.
Growlllllllllllllll
The wyvern growled at him upon his action, it wasn't sure what Williams was trying to achieve. It's beastial instinct kicked in as it accepted Williams challenge, it folded it's wings and dived down swiftly.
