The Bridge Key (橋の鍵 Hashi no kagi) is a key that is exclusive to the Archanea Series of Fire Emblem. The Bridge Key is, in essence, a skeleton key designed to allow its holder to bypass all locks imposed on drawbridges, thereby making them traversable. The function of this key is rendered obsolete by the presence of the Master Key and Thief characters, both of whom are capable of indiscriminately breaking all locks.
