Viễn cảnh Cấp-K là những tình huống giả định có thể có tác động mạnh đến sự bình thường hoặc thực tế, bao gồm cả ngày tận thế. Tổ Chức liệt kê ra những gì có thể xảy ra trong các sự kiện này và các tác giả trên trang wiki thường đề cập đến các kế hoạch dự phòng này … hoặc những lần chúng đã thất bại.
Trang hợp tác này tồn tại để ghi lại tất cả các Viễn Cảnh Cấp-K được sử dụng trên trang wiki.
Lưu ý

• Không có khái niệm chính thức cho bất kì Viễn cảnh Cấp-K nào. Trang này không nên được coi là nguồn "chính thức". Xin đừng làm phiền các tác giả vì "sử dụng sai" các viễn cảnh này.
• Danh sách này dùng để mô tả, không phải liệt kê. Các định nghĩa dựa trên việc sử dụng trong các bài viết, không phải bất cứ ai nghĩ chúng nên có nghĩa. (Đối với các danh sách trước đó với các định nghĩa được tạo ra, hãy kéo xuống.)

Một chút về cách viết: (Tôi coi các biến thể ngữ pháp này là như nhau.)

+ hiện

• Các viễn cảnh thường như sau: Viễn cảnh Cấp <Chữ cái>-K <mô tả/ngày-tận-thế>
• "Viễn cảnh Cấp-K" và "Sự kiện Cấp-K dường như được sử dụng để thay thế cho nhau. Không có logic nhất quán cho nó. Viễn cảnh được sử dụng khoảng gấp 4 lần thường xuyên hơn sự kiện trong lần tìm kiếm ban đầu của Petrograd (tác giả gốc).
• Viết hoa (Cấp-XK Ngày…, cấp-XK ngày…) và cắt ngắn (ngày-tận-thế, "ngày tận thế", ngày tận thế) dường như không có bất kỳ tiêu chuẩn được thiết lập.

Bạn muốn giúp đỡ?
Làm ơn! Đây là bài viết hợp tác. Xem các bước sau đây:

+Vậy bạn muốn liên kết một bài viết?

Vậy bạn muốn liên kết một bài?

• Xin vui lòng, làm điều này! Bản đầu của Petrograd chỉ bao gồm các SCP được tag vì vậy những câu chuyện và các bài viết khác cần được chú ý. Chi nhánh Việt Nam cũng có tại đây
• Hãy chắc chắn rằng bài viết vẫn đang có xếp hạng tích cực (duy trì ở mức +1 hoặc cao hơn trong 24 giờ) trước khi thêm liên kết: rất đau đầu khi phải xem qua và dọn dẹp sau đó
• Nếu bài viết sử dụng tiền tố có tồn tại và phù hợp với định nghĩa chung, chỉ cần thêm liên kết và cập nhật bộ đếm (# SCP, # Câu chuyện , # Khác). Có thể thêm tiêu đề thay thế nếu nó mới và nghe hay.
• Nếu viễn cảnh không nhất quán với cái khác trong tiền tố đó, HOẶC là bài viết đầu tiên sử dụng tiền tố, HOẶC chỉ xuất hiện trong -J, vui lòng thêm nó vào bảng thích hợp bằng định dạng này:

||~ Tiêu đề ||~ Định nghĩa ||~ Bài viết ||
|| || || ||

• Nếu cần cả tab, đây là một định dạng cơ bản:

Vậy bạn muốn bổ sung hoặc cập nhật một định nghĩa?
Có thể bạn là tác giả của một viễn cảnh sử dụng một lần hoặc không nhất quán hoặc có thể bạn muốn cập nhật một định nghĩa chính đã lỗi thời. (Hoặc, bạn biết đó, nếu nó có thể tốt hơn.) Cứ làm đi! Nhưng phải nhớ rằng:

• Các định nghĩa nên được dựa vào việc sử dụng. Chỉ tạo hoặc cập nhật định nghĩa để phù hợp với việc sử dụng chúng trong các bài viết.
• Nếu cách sử dụng và tiêu đề thực sự khác với tiền tố hiện tại của nó, hãy xem xét việc thêm nó vào "Sử dụng không nhất quán".
• Rất hữu ích nếu bạn thêm một ghi chú xuống phần "Short description of changes (Mô tả ngắn gọn các thay đổi):" trước khi nhấn "Lưu”
• Không nên thêm định nghĩa mà không có một bài viết thành công, được liên kết!
