Zuzu was originally a nickname for an oc that I used to use. Once I started to be on the internet more often I decided to use that nickname for anytime I made a profile on anything. I just like it and have used it for years now.
The language is Latin! Draco is the Latin word for 'dragon' or 'snake'.My family all made pen names that had shadow in it somewhere. We'd take a name, animal, or creature we liked and something else and mix it all up to make our pen names. I really like dragons so I took the name Draco, which translates to dragon in some language I can't think of right now, and mixed it with shadow and dragon to come up with Draco Shadowdragon. I know totally repetative, right?
