A Locke history lesson

Though we learned a little bit about the Locke ancestors in season one, season two introduced us to Benjamin Locke (Carson McCormack)—a teen during the Revolutionary War who helped his father make weapons for the colonial rebels, then used his metalsmithing skills to craft the first magical key. Flashbacks showed us how British Captain Frederick Gideon (Kevin Durand), a very malevolent dude even before becoming a demon, first opened the Black Door (basically, a portal to an evil dimension) in a sea cave near Keyhouse. We also saw how Benjamin discovered “Whispering Iron”—the material that makes up the “bullets” that shoot out of the portal; any human struck with one becomes possessed—and used it to make the Omega Key to secure the lock on the Black Door. It’s implied that he and his sister then made even more keys, using a magical ritual passed down to future generations of Lockes, including Duncan and Tyler.
