Bloodsaurus

A monster born mysteriously from the remains of a dragon. Its bones are dyed red. There have been many peculiar reports pertaining to these dragons, such as some targeting specific people, or others showing signs of trying to communicate with others. Because of this, some believe that these dragons are created from dragon carcasses which have been possessed by a deceased human's soul. But this has proven difficult to confirm, and is, but yet, merely a theory.
