There's a part of me that's wondering if the Archon's filming isn't part of a residual order left behind from Charlie. Could it be possible that decrypting wouldn't override that compulsion, unless Wanda, Stanley, Ansom or Parson actively tells them not to transmit these things?
I can't really see it happening, because of how decrypting totally re-wrote Ansom's perspective. It seems that the Archon's would be similarly re-written, but if its implanted into their minds that transmitting such information is a) what they do and b) not a betrayal of their side then i guess it could be possible.
Taking into account that they are the specialist units of the Arkendish (is that canon? or am I just assuming/inferring it?), it may be that feeding back everything of importance to the Arkendish is integral to their nature regardless of who their loyalty is to, and if somebody just happens to be attuned to the Arkendish the nthey get that info.
Wild speculation, probably well off base, but it just seems to me a possibility.
Also, having Parson effectively tied into Gobwin Knob for (at least the beginning of) book two seems pretty cool to me. Looks like he will be re-claiming his position as chief warlord and directing the battles form before, a spider at the heart of the web. kinda cool i reckon
(does anyone recall who the fictional detective is that is paralysed and unravels murder mysteries from his wheel chair without actually seeing the scenes and perpetrators, 'out sherlock holmesing sherlock holmes', as it were - same as that but committing murders / warfare and conquest from afar)
Anyway, I am now much more convinced than ever that breaking the can't cross hex-boundaries will provide a suitable dramatic moment when Parson forces his way through. possibly for romantic reasons. In book one he claimed control of his mind, in book two he can gain control of his body. Or at least, enough to override Erf physics (which i include the mental compulsions in as well as the physical restrictions) with Earth physics.
Oh, and another excellent piece of artwork!
