Previous Post I completely disagree with you. "Utterly alien is just another word for cipher" No. Just no.

Yes it is. Human behavior runs a broad gamete from saint to psychopath. Past that broad gamete you get something a human writer can't actually write, not really. You get something like Chthulu, a creature which can only show up very briefly because utter-alieness isn't writable by a human writer, and translates into bland cipherness when you try.
