There's a file that should be called "blank.php" you can use this to make a new page (not on pages.php) that you can use any PHP and HTML coding you want.
Duplicate this page, rename it something else, then use something like:
PHP Code:
$article_title = "PAGE TITLE HERE";
$article_content = "ARTICLE CONTENT HERE. You can use HTML in this space but remember not to use a 'double' quote or it'll mess up.";
Also more complicated but you can make sub-pages so you don't have to make tons of pages and can have you entire quest in one page. I think Kaeliah made a tutorial somewhere, let me find that
