Give me an overview of the most important tendencies in art (literature, visual arts, that sort of thing) over the years in ER's universe. What frightening, vicious and possibly beautiful things came after postmodernism?
How pervasive is UWM propaganda in regular life at peacetime on the average UWM world?
What lifeforms is or was Xeno Spit extracted from?
Do cats still exist in this dystopian future? Have they changed through long years (was it a thousand? More? Less?) of presumably focused breeding? What about dogs?
Have any of Earth's old cultures mostly survived in the future, or have they all been assimilated, intermingled and just plain changed to the point of unrecognizability? There are the Wayfarers, yes, but other than that little bit?
How have the Wayfarers changed over the long, long years? Can't imagine they'd be the same now as they were many centuries ago.
Does a Space Pope actually exist? Does Raptor Jesus appear in any popular iconography of the past centuries or the present?
Do people outside ARM experience overshots in their daily lives?
How is farming conducted in the far future on more technologically advanced planets? Do they have dedicated futuristic farm planets (similarly to Hephaestus' factory world status) or is that too impractical? Do food shipments happen?
Does an interstellar economy exist, and if yes, to what degree? Are there galactic market crashes?
Are there junkyard planets or star systems (or patches of interstellar space) where they put all their crap when it reaches unmanageable levels?
Does your sister have any potential plans for ER art? A landscape, for instance, to contrast with Sean's character pieces? Or is that unlikely to happen?
