During the the "Legends of Tomorrow" winter finale, the Legion of Doom -- Malcolm Merlyn, Damien Darhk and Eobard Thawne -- finally acquired the amulet pieces they were so desperate to obtain. When Thawne assembled the seemingly unrelated baubles, he revealed that they were a compass, one which pointed the way to the famed Spear of Destiny, described as having the ability to "rewrite reality itself," a description echoed by Nate Haywood during the "Legends" midseason premiere.

So far, two pieces of the amulet have been recovered on "Legends of Tomorrow," as well as the six-meter pol that was in Rip's possession, but there are still more pieces to be assembled. And wwhile the Spear of Destiny may sound like something from "Indiana Jones" or Keanu Reeves' "Constantine" film, it actually has a rich history in DC Comics.

The Spear of Destiny first appeared in 1977's "Weird War Tales" Vol. 1 #50. In this issue, the Spear of Destiny was called the Spear of Death, as it was the blade that cut the side of Jesus Christ during his crucifixion, an event that's also crucial to the "Legends of Tomorrow" Spear. In DC Comics lore, Adolf Hitler utilized the Spear to control the mind of any metahuman or superpowered person thanks to the artifact's Sphere of Influence -- essentially, anyone who entered the Sphere would be under Hitler's control.

The Spear was later used by Superman against the Spectre, the embodiment of the Spirit of Vengeance whose powers had grown out of control. During "Final Crisis: Revelations" the Religion of Crime used the Spear to bond Vandal Savage with the Spirit of Cain (Adam and Eve's son, who killed his brother in the Book of Genesis). Savage used the Spear to wage war on Gotham, but was overtaken by the newly reborn Spectre, who used the Spear to set the world right again.

So far, the Spear's comic book history has two obvious connections to "Legends of Tomorrow" -- Vandal Savage, and the Justice Society of America. Since Savage was killed in the show's first season, it's easy to see how the series will will likely connect the Spear to the World War II-era Justice Society. In "Legends," the JSA was the initial team of superheroes who protected the Earth from threats. In the second episode of the season, the JSA was fighting Nazis in 1942, which was where Thawne acquired the first amulet. In the fifth episode of the season, "Compromised," Darhk acquired the second amulet from a KGB operative. Together, the amulet pieces formed the compass that leads to the Spear.

An amulet that points to a spiritual relic from WWII? Sounds a lot like the plot to the first Indiana Jones film, "Raiders of the Lost Ark." Interestingly enough, the Spring premiere of "Legends" was titled "Raiders of the Lost Art," and featured a young George Lucas as a character. It's clear the show is going down this WWII/spirital relic path. Another Indiana Jones film, "The Last Crusade," also dealt with spiritual relics from the WWII era, namely the Holy Grail. Is it coincidence, then, that the Legends will travel to Camelot in episode 12, "Camelot/3000?" Considering King Arthur's connection to spiritual relics like the Grail, one can assume another piece of the Spear may also be in Camelot.

When Hitler had the Spear in the Golden Age, he could use it to control the mind of metahumans and superheroes. We know that after many seasons on "The Flash" and "Arrow," Merlyn, Doom and Thawne have been thwarted time and time again by superheroes. Thawne especially, since his nemesis, Barry Allen, is a metahuman. It's possible that Thawne, knowing that his death and Darhk's death are inevitable, decided to step back in time to acquire the only thing that could stop those with super powers, the Spear of Destiny.

Since the Legion of Doom exists mainly on "Legends of Tomorrow," rather than using the Spear on Barry or Oliver, the Legion will likely use the Spear on the Legends, creating a timeline where the metahuman Legends are against any non-metas. Throughout this season, characters like Ray Palmer have wondered if they really were heroes despite not having super powers like their metahuman friends. It's possible that Ray Palmer, Mick Rory and Sara Lance will find themselves unaffected by the Spear, allowing them to prove to be the Legion's undoing.

Rip Hunter is another Legend without metahuman abilities, and Thawne said that Hunter was the key to finding the Spear. It's possible Hunter's return will both hurt and help the Legends. As we saw in the winter finale, Hunter has been directing movies in 1967 Hollywood. Now that we know that Rip has no memories of his life before 1967, he won't be able to help the Legion of Doom acquire the rest of the Spear. The Legion could use Rip as leverage, however, to exchange his life for the Spear.

However things play out in the back-half of the Legends' second season, it's apparent that the Legion of Doom and their newly acquired weapon will be at the center of things. And as the villainous team's tendrils expand outward, drawing Captain Cold into their inner circle as they infiltrate the rest of The CW's DCTV series, viewers will learn just how powerful the Spear truly is.
