I'll really think that I can't do this but...I just found my old drawing (if interesting, I was made it in 2015 - imgur.com/acjNOEA)

Maru is really small sand dragon, and rarely breathes fire. Very smart, but shy. He lives in library, in one mansion. It is perceived as a full-fledged member of the family, and not just as an animal. Very likes to read books, especially likes rare, about magic. Like many dragons, has a pronounced empathy. A peaceful and unselfish creature that behaves like a scaly cat
