Fire Emblem: Ankoku no Miko

Fire Emblem 64 was a cancelled Fire Emblem game for the Nintendo 64. It was first mentioned in July 1997, in an interview with Shigeru Miyamoto. One year later, in September 1998 Fire Emblem 64 was officially announced in various Japanese gaming magazines. However, two years after that, in September 2000, the game was cancelled and instead development was moved onto Fire Emblem: Ankoku no Miko, which was later renamed Fire Emblem: Fūin no Tsurugi. No information or even screenshots were revealed for this mysterious title.

Speculation
Some people suggest that Fire Emblem 64 eventually became Fire Emblem: Fūin no Tsurugi, due to the sudden change of development, but there is no real evidence to support this. A few believe it instead became Fire Emblem: Souen no Kiseki based on early images of the GameCube title, but there is no evidence to support this either. Others, many Japanese fans, believe it was mean to be a continuation of the Akaneia saga, based on several hints from the series's creator, Shouzou Kaga, which showed he was deeply interested in making such a game.
