All the pages are available in an easy to read format over on e621. Just look up Nicolaswildes_(artist) in the search field over there, then scroll down and click on one of the posts that looks long and thin - if, in the upper left-hand corner, it says:

"Pool

Zistopia AU by NicolasWildes"

then click on that, and the first post will be the first post of the series (from there, just click on that, and then it's easy to navigate - just use the "Next" button). I wanted to give you a direct link to the pool but it seems dA is not accepting my comment (considers it spam) due to that. If you'd like, I could give you a direct link to the pool in a private note or something.



Unfortunately, the "finding specific pages" isn't much better on e621 than it is on tumblr (but at least the stuff is easier to navigate, and arguably, read).



And that way, you can just use the tumblr for all the text posts the author released which serve to set up some portions of the backstory of the universe.



Dunno if you've already found this way or not (or whether you've already read them all already), but if not, I can't recommend the comic enough.
