While never directly stated in our MoS, we used to abolish links to redirects from page content, opting to link to pages they were redirecting to directly. In retrospect, this was a bit silly. I just had to modify 4 articles pointing to Jockington’s section on Hometown/NPCs to point to his new article instead.
I suggest we follow WP:NOPIPE instead, so that we avoid problems when suddenly characters become important enough to spin into their own articles, and have cleaner wikitext.
