I think there is no direct borrowings, just some common elements and nods.

We made them up ourselves.

you guys are great on storytelling, loved both Bookwalker and Final Station and would be amazing to have another Bookwalker game even though it probably wont happen, Im probably buying every single game you guys make anyway.

Made up from scratch, but clearly a blending of many genres that have very popular books or writers. Harry Potter for the wizards. Asimov and Clarke for the zealot AI.

I thought many of them were interesting enough with their juxtapositions, even if most stolen objects were based on something from our world.

The way this game is made, is suited for DLC. Each new DLC could be 3 or 4 new stories for some denaros. Since each story is unique and not tied to anything other than the Ettiene himself, its very reasonable to expect more stories.
