{{Quote|Some of you may be wondering - "What's up with this unhealthy obsession with the number 7?"  This page offers ''some'' insights.|[[Brian Jarrard]], linking to this very page<ref>http://www.bungie.net/News/content.aspx?cid=14650</ref>}}

{{Quote|Cause that's the best number. It's like rock. Nothing beats rock or 7.|[[Michael Wu]]}}

[[Bungie Studios]] has long enjoyed using the number '''Seven (7)''' in its games in many prominent ways<ref>[http://marathon.bungie.org/story/seven.html Marathon.Bungie.Org: The Number Seven]</ref>. [[Ensemble Studios]] and authors also have certain obvious seven references in their works about ''Halo''. While almost anything can be made into a reference to something with effort or constructed accidentally through [[wikipedia:pareidolia|pareidolia]], the following attempts to list the intentional references Bungie placed into ''Halo'' for the fans to find. As such, not all of these references may be fully accurate, and many of them may be proven to be false at any time. Bungie's obsession with the number seven may be attributed to (or be a determining factor) why [[John-117]] is considered lucky, as 7 is considered a lucky number. In spite of the fact that the number seven is featured extensively in Bungie's work, it has generated an aura of [[wikipedia:apophenia |apophenia]]. This cultural nuance can be compared to the [[wikipedia:23 enigma |23 enigma]].
