Thank you! Yay! All I need now is to get a commission to write a Blake's 7 trilogy, or perhaps ghost-write a companion volume to The Children of Hurin on the Tuor story!

it means the narrative is taking on a life of its own, and not just having you (one) consciously manipulate what goes into it.

Oh that's a really good point: and narrative, like most other things in life, is generally worsened for being over-controlled.
