How large? Well now, considering the size of an average Pixie- it was Huge, at least to me. In comparison to a normal person? It was stull pretty large and of a substantial size. It was not only large on it's own, but also had something of nearly the same size that was accompanying it on it's endeavor. Following closely along behind if you will.
I was not frightened by this, but rather soothed in knowing that I have something of an extremely larger scale than life, watching my back. It is also a reminder that people should never meddle in the affairs of dragons. For you are crunchy and taste good with ketchup.
