The S (for 'shortcut') and IW (for 'interwiki') templates are intended to reduce linking codes in a simpler, more convenient way so pages don't get too crammed, inherently increasing the amount of bytes the page has to load. The S template is to directly link inside this wiki, you use it for existing articles found here, whereas IW is to link to external wikis also hosted by FANDOM in case we don't have or don't require an article for the subject (but honestly I'm not keen to linking to external wikis as we don't receive feedback back from them).
