In what seems to be a Tri-Ace staple, the Seraphic Gate is a secret dungeon or level that can only be unlocked once you save at the final save point. Upon doing so, you can finally view it on the world map. What's unqiue about the Seraphic Gate is that you can unlock many Einherjar that you haven't already done so, or you have and they've left. There are also contained the best weapons and the best items you can find. There are also bosses you can fight for experience and to get new Einherjar
