Canon Rumor is the name for information, stories or "facts" which could be considered as 'in-story rumor,' based on its context within the source material. Some facts from BattleTech's history are based on mis-direction perpetrated by in-story characters or organizations, such as ComStar or the Word of Blake.
The term 'canon rumor' came about during FanPro's oversight of the BattleTech franchise, when Interstellar Players was published. The book provided different alternate 'truths' to the history and events of the BattleTech universe and supplied players with alternative storylines with which to play. The Jihad Hotspots series of titles is often considered to be composed of half-truths and rumor, based on the communication breakdown associated with the corruption of the HPG network during that conflict.
