Au contraire, I like wolves. A lot, actually (if you don't believe me, you can read "Building a Mystery" on lotrff.com or Ficwad). That's why I have a bit of a problem with the "evil wolves" how they're usually portrayed in Tolkien's works. He's drawing a lot on fairy-tales and such and connects wolves per se with evil (see the werewolves or wargs). Which is unfair, in my humble opinion.

As for Teitho - that sounds like an idea to me! Something like "Darwin's Heirs". Mhm, I have to ponder that a bit, maybe we could really do something with it. Who knows!
