(Taken from the article on STEU)
Most fan fiction series on STEU are sourced with external links to sites that host the fan fiction in question. This is due to the site's rule on having no fan fiction actually been on the site as it endeavours to be a fanon resource (in a similar way to MA for canon and MB for non-canon material) rather than a fan fiction hosting site. Not all fan fiction will be available as over time online links will go "dead", but these are usually labelled to notify a reader that the external link is no longer active.
