This makes me happy.
So more characters and a story arc for delight_in_wt has developed in my head, and I've posted a couple more entries to it which I've enjoyed re-reading and which are more-or-less intelligible even to people who aren't World Tree fans. Which is to say: there's still plenty of references to the setting, but in a pick-it-up-from-context as-you-go-along mode. Which is what I generally aim for in my fantasy anyway.
Given my new excitement, I figured I'd take a stab at actually selling it instead of telling people about it and adding "but it's awful". I like it now. I invite you all to take a look, and suggest you start with the second entry, especially if the first entry is impenetrable.
