I tend to take my screennames from mythology. One of them, my most (in)famous, means Child of the Chaos and Fire god. It means that, though it's really one word. The reason I don't use it here is for privacy reasons, of course. As I said; it's my most (in)famous screenname.
Dryad is the second one. Because Dryads are mostly female, but there are male dryads known in mythology. A nice opposition to me, myself, as I am physically nearly fully male, as in: well over 90%, but mentally much like an even split. And I like something that can be both either sex and both sexes.
The avatar is because I feel torn and chaotic, at the moment. Which I think this typo-fearie pretty much demonstrates. (drew it myself, and I have quite a few more pics I might use in the future, ready to replace.)
