The problem is that you are typing Nora Valkyrie instead of just Nora Valkyrie

Double brackets mean that you're doing a link to an article on the wiki, so it's looking for a page titled "Rwby.wikia.com". Either use the other type of link to go to the URL called rwby.wikia.com, or just type Nora's name to get to the Nora Valkyrie article.
