These are the sort of links Google would approve of as natural links:


 * Links in articles and navigation to other subdomain/wiki-specific links.
 * A limited selection of advertisement links and any natural links to the parent domain.
 * Natural links in articles that go to other domains - it is blatantly obvious when this is the case, like with cultural references to stuff outside the wiki's scope.

And then there's randomly injected links that are put in outside of their contextual merit.

I think Google treats independent wikis as different domains though they are different subdomains, its interesting to wrap my head around it actually.
