Solution to #2: main

    The lack of an answer box here doesn't leave you with many options. The bookmarked locations indicate that you should change the URL (e.g. http://quest.skule.ca/1T6/act3/main/progress1/), and indeed that method allows you to view other pieces of this puzzle.
    /progress1 clarifies the main mechanic of the puzzle and indicates that a page called /progress2 exists. /progress2 leads you to /room126, and they both hint toward another page which is the “sister” of /room126: /room124. This page is also hinted at by /wreck, which is otherwise a red herring.
    /room124 concludes the string of fanfiction and hints directly toward /treasure, which is effectively the answer to this puzzle since no answer box exists.
