Just one page to go after this. Are you ready for art to bleed?
The reason for this strict control of what can be seen is sadly obvious. Artists and other creatives sell their souls to Infernals at a rate so high that a whole department of the circles of hell deal with them exclusively to prevent a bottleneck. The things they create are often tainted relics which can warp reality and the minds of the viewers, and so everything has to be scrutinised carefully. Externals too can bestow artistic excellence on cultists, although this is very rare.
