Thinking about some background stuff we were discussing last session. In your Duskwall, do you have/make use of photography (either the Victorian spirit or Kirlian (electroplasmic?) aura variety?
Spirit photography sounds like a positively lethal idea to me, but then how far would well-heeled types go capture a snapshot of their loved ones before their trip on the funeral barge to Bellweather? Sounds like a side job for a Whisper and some kind of esoteric gadgetry.
Leading on a little from that, how about newspapers? We all know how important control of the media is – how would that work in Duskwall, especially given the variety of groups looking to further their cause? Thieves with a printing press? Might be interesting to consider.
