I just read up on the series on Wikipedia...

heres what the Fire Emblem Gaiden article says...
Fire Emblem Gaiden (ファイアーエムブレム外伝, Faiā Emuburemu Gaiden?) was released exclusively in Japan for the Famicom in 1992. It is the second game in the Fire Emblem series, and serves as a side story to the original game ("Gaiden" is literally Japanese for "side story"). Set in the same game world, the events of Fire Emblem Gaiden actually takes place on a different continent, and thus have no bearing on the first game's narrative. However, several characters from the original game, such as the pegasus knight Paola, do make return appearances. |
It sounds like the game is a sidestory but does not closely coincide with the first game.
