Paradoxian was a wiki network dedicated to various older Paradox games. At some point registration and anonymous editing was closed due to spam issues, and the owner of the wiki disappeared not long after.
With the inability for anyone except already registered users to edit the wikis, they slowly became more and more outdated.
The Victoria 2 Wiki, Europa Universalis 3 Wiki, Hearts of Iron 3 Wiki, and Europa Universalis: Rome Wiki were all cloned to the Paradox Wikis so that they could continue to be updated.
The Victoria 1 Wiki, Europa Universalis 2 Wiki, Hearts of Iron 2 Wiki, and Arsenal of Democracy Wiki were all lost when hosting for Paradoxian expired late in January 2015.
