Hi, welcome to Aselia! Thanks for your edit to the Richter Abend page.
Dummied data will not be acknowledged
Your information on Richter's page has been deleted because it relates to content that is not accessible legitimately within the game as it is designed to be played. You're right that an outright quotation of these things is not permissible to begin with, as it is information that players should experience for themselves by playing the game proper, and this wiki does not represent the function of a game script. It is an encyclopedia and translation resource. All text within our pages should be appropriately summarized to form a historical narrative. Quotations are allowed on content articles as long as they do not compose an entire paragraph or dialogue, and if the precise words are not particularly relevant, they should be integrated as descriptive text rather than outright quotes. In contrast, quotations are a standard part of our individual arte pages as the quoted words relate specifically to the artes in question. Regardless of its validity as content, it cannot be used if it relates to dummied or unused data as this is not part of the game in the official sense. We treat such things as if they simply do not exist. And they are always prone to speculation and guesswork, which goes against encyclopedic content as a whole. Our rules on this concept are explained in detail on the Manual of Style.
I see Mayu has already informed you of our policy. This rule includes unintended elements of the game, such as the one you added on the Keterburg page.
