Begun on March 16th, 2006, the Silent Hill Wiki has since grown to 2,147 articles, and covers multiple aspects of the Silent Hill universe, including the numerous game titles released by Konami, the 2006 film, and the series of comics published by IDW Publishing.
Articles content includes character information, puzzle solutions, item descriptions and game synopses. The wiki aims to be as professional as possible as it is the biggest Silent Hill encyclopedia on the internet. Silent Hill Wiki has forums, a chat room, blogs, and polls for everyone to participate in and discuss anything they like. The wiki is also affiliated with many other fan sites.
Silent Hill is a very mysterious, personal series. Many things in the series are open to interpretation, or have origins left unexplained. Silent Hill Wiki is edited by fans, for fans. Fans tend to hold varying beliefs and opinions about the series. While there are given facts in the series, there is also a lot of mystery in the series. The wiki should never be used in a manner which tries to impose various beliefs on the reader, or else it risks being biased. The wiki should try to be as general and neutral as possible, and debates should always be respectful and dealt with accordingly.
It should also be noted that wiki is an unofficial fansite, which has been edited by hundreds of visitors. Just because one user edits an article, it doesn't necessarily represent the view of the entire community of the wiki. Information added to the wiki always has the potential to be incorrect, however, the success of the wiki is also built upon this risk-taking and learning.
Where does Silent Hill Wiki gets its information?
- The primary information source are the games themselves, including the memos found in-game.
- The Book of Lost Memories provides a lot of information covering SH1-SH3, such as ages, occupations, etc.
- The game manuals. For example, Homecoming's reveals all of the character's ages.
- Some of the information has been obtained by deductive reasoning. For example, Another Crimson Tome states "Cynthia was 13 years old 16 years ago." 13+16=29, thus Cynthia is 29.
- The strategy guides contain some good info. For example, SH4's strategy guide reveals Walter was born 34 years ago.
- The novelizations of the games, written by Sadamu Yamashita in Japanese and translated by Lady Ducky to English.
