A plant run by Mose in the Dana region, the Secret Factory was used to covertly create many weapons for the Liberation Army, including the Fire Spears, which the Liberation Army used to defeat one of the Six Great Generals, Teo McDohl and his Armoured Cavalry. Upon the completion of the Fire Spears, Mose and his subordinates, including Ronnie Bell, travelled to Toran Lake Castle, joining into the Liberation Army there, where they stayed until the end of the war, the Secret Factory having served its purpose.
