This is Tad (real name Thaddeus), an earth elemental who ran away from his creator Edward Oliver, an architect/dabbler in magic. An elderly lady picked him off the streets and took care of him for the last year. Tad is two, but has the body of a twelve-year-old and the fun starts here. He is out of control, does what he wants when he wants with no regard for the rules at all. His tumultous start with Edward left him with a strong dislike for teachers and men, although he tolerates women much better.
As an earth elemental, all he can do (well, chooses to do) is destroy stone/rocks. He likes flashy things like abilities and so if a person can't do something fascinating in his eyes, they're not worth getting to know most of the time. I forgot to mention the one rule he has: don't tell him what to do. Destruction will follow.
