The MediaWiki:User-identity-group pages will only change the text of the label, but for ALL in that group. You could change the sysop to "Writer" and ALL the Admins would be relabeled to "Writer". To individualize it you'd need to use UserTags.

As a short-sighted workaround, since you are the only active Admin (the fanfiction wiki with your name, yes?), Editing the MediaWiki sysop page would give you what you want.

For a proper resolution, Someone would have to provide tailor-made UserTag code for you to copy -OR- you'd have to make someone a temporary Admin so they could do it for you.
