Ask Novil questions about Gaia

Now that the end of Gaia is in sight, it's time for the last "Ask Novil questions about Gaia" post. Here are the previous editions: [1], [2], [3], [4].

A lot of open questions have been answered in the last 100 published pages, but I'm sure some of you still have questions about the plot and the setting of Gaia and everything related to it. So please put them in the comment section of this post.
