Pywikibot should have good support for Orain wikis.
Pywikibot doesnt have any family classes for Orain wikis.
They have a test wiki : http://test.orain.org/wiki/Main_Page , which may be useful for testing.
Ideally we would also add an Orain wiki to our automated test suites; see https://travis-ci.org/wikimedia/pywikibot-core for the WMF dominated list of tested hosts.
@NDKilla, please advise if you're not interested.
