The Dark D. Fort is a fortress located in Lament Woods. It is own and operated by the Dark Dragon Army.
Finding a strange fort in Lament Woods, Ryu and Nina decide to investigate. They soon learn that the fort belongs to the Dark Dragons and continue to explore. They soon discover a man they believe to be Tuntar's chief surrounded by guards. After the guards are defeated Tuntar's Chief insists that they take the Dark Dragon Army's weapons before returning to Tuntar, if the party continually refuses then the boss battle against Pog will be skipped and Bo will arrive. If the party agrees to take the weapons, the fake chief leads Ryu and Nina to an empty cell and locks them in, revealing himself to be a general in the Dark Dragon Army. Ryu and Nina then face the two headed creature Pog in a boss battle. After Pog's defeat Bo arrives freeing Ryu and Nina. Bo explains how he freed the real Chief of Tuntar during the confusion and joins Ryu and Nina in their battle against the General. After the battle the General retreats and Bo officially joins Ryu's party.
