[[File:TheCage.png|500pxthumb|right|500px|Lucifer's Cage.]] Lucifer's Cage is a prison located in [[Hell]], and was designed by [[God]] to hold [[Lucifer]] captive.

After [[Lucifer]] was banished from [[Heaven]] for defying [[God]] due to his corruption from the [[Mark of Cain]], he twisted a human [[soul]] into the [[Lilith|first demon]]. After this, God sent [[Michael]] to imprison Lucifer in the Cage which was locked with 600 mystical seals.

In 1972, [[Azazel]] possessed a [[Father Lehne|priest]] at [[St. Mary's Convent]], and killed eight nuns in the chapel. This enabled him to speak to the imprisoned Lucifer, who used the [[The Nun|head nun]] as a conduit. Lucifer tells Azazel that Lilith is needed to break [[the 66 Seals]] that hold him captive in the Cage and that he needs to find a very "special child."<ref name="four22">[[4.22 Lucifer Rising]]</ref> This leads Azazel to recruit [[:Category:Special Children|select children]], including [[Sam Winchester]] and to set in motion events that subsequently lead to the breaking of the 66 Seals.

In 2008, after [[Dean]]'s return from [[Hell]], [[Castiel]] reveals that Lilith is trying to break the seals that lock the Cage in order to free Lucifer. Dean later learns that the first seal was broken when he was in Hell, and broke under torture and began torturing [[souls]] himself. Sam continues clandestine missions with [[Ruby]], developing his powers even though this involves drinking [[demon blood]], believing that killing Lilith will stop the Cage being opened.[[Image:Luciferscage.jpg|300px|right|thumb|Sam/Lucifer and Michael/Adam fall into the Cage.]]In 2009, Sam unknowingly releases Lucifer from the Cage by killing Lilith at [[St. Mary's Convent]]. Lilith is revealed to have been the last of the 66 Seals. As Sam and Dean attempt to find a way to stop Lucifer and the impending [[Apocalypse]], [[Gabriel]] tells them that the [[Four Horsemen of the Apocalypse]] all own rings that together can reopen a portal to the Cage anywhere. After collecting all the rings, Sam comes up with a plan in which he will allow Lucifer to [[possess]] him, and then force him into the Cage. The initial attempt fails, but when Lucifer confronts Michael at [[Stull Cemetery]], Sam activates the rings and as the Cage opens, he manages to gain enough control to force himself (and Lucifer) into the Cage. [[Michael]] (in possession of [[Adam]]'s body) tries to stop him but is dragged into the Cage as well.

Later, in [[Stull Cemetery]], Lucifer faces [[Michael]] who appears using [[Adam Milligan]] as a [[vessel]]. Lucifer tries to dissuade Michael from the fight, blaming their conflict on [[God]], and suggesting they walk away. Michael counters that he must carry out God's orders, and that it's his destiny to kill Lucifer, who is evil. Just then Dean arrives in the [[Impala]], Def Leppard's "Rock of Ages" blaring. Dean tries to talk to Sam, inside Lucifer, but Michael tells him it's not his fight anymore. Castiel arrives and throws a Molotov cocktail made with [[holy oil]] at Michael, causing him to vanish temporarily. Lucifer turns and blows Castiel up with a snap of his fingers. Then, as Bobby begins shooting him, he snaps his Bobby's neck.

Lucifer starts to beat Dean, taunting him, saying he will kill him slowly and make Sam feel it. Dean doesn't resist, just telling Sam he won't leave him. As he Lucifer goes to land another blow, he glances at the Impala, and suddenly all Sam's memories of life with Dean rush at him, allowing Sam to take control over Lucifer. He tosses the Horsemen's rings to the ground, and recites the incantation to open the Cage. He and Dean look at each other one last time, but as Sam goes to throw himself in, Michael reappears. Michael tries to stop him, but Sam drags him into the chasm too, and it shuts.

Dean has himself purposefully "killed" under medical supervision, so he can plead with [[Death]] to rescue Sam and [[Adam]] from the Cage. Death agrees to rescue only one of them -- Dean chooses Sam. Death makes a wager with Dean, that if he will wear Death's ring for one day, and perform his duties, then Death will rescue Sam's soul. he He tells Dean that he will be able to contain the part of Sam that will be damaged from his time trapped with Michael and Lucifer behind a "wall" in Sam's mind, although he can't guarantee how long this will maintain. Although Dean fails to wear the ring for a day, Death agrees to retrieve Sam's soul, which he returns to Sam.

Sam starts remembering a portion of events that happened when he lacked a soul. After Sam and [[Dean]] resolve the murders, Sam falls onto the floor, shaking uncontrollably, where he recalls some of the torture he endured in Hell by [[Lucifer]], where he is seen covered in flames.[[File:SamInHell.png|350px400px|right|thumb|[[Sam Winchester]] in Lucifer's Cage.]]

After getting a [[Hyperbolic Pulse Generator]] from [[Arthur Ketch]] of the British [[British Men of Letters]], the Winchesters, [[Castiel]], [[Crowley]] and [[Rowena]] team up together to return [[Lucifer]] to his cage. Using [[President Jefferson Rooney]]/Lucifer's mistress [[Kelly Kline]], the group lures Lucifer to a motel where Sam uses the Hyperbolic Pulse Generator, a device capable of expelling a [[demon]] from their [[vessel]]. The powerful pulse beats Lucifer back, as Rowena casts a spell to send Lucifer's essence back to the Cage. After exchanging words with Sam, Lucifer vacates the president's body, his essence swirls below the ceiling before going through a heating vent in the floor. ===[[12.13 Family Feud]]===Crowley reveals that he perverted Rowena's spell to send his essence back to his discarded vessel [[Nick]] rather than being sent back to the cage. Crowley had a dozen of his most loyal demons study the cage at the molecular level and replicate the material used in creating the chains that bind him. ===[[12.15 Somewhere Between Heaven and Hell]]===When Lucifer escapes his chains and tries to kill Crowley, he reveals that he also had the runes and spellwork from the cage carved into every molecule of his vessel, allowing him to negate Lucifer's powers and effectively torture him. ===[[13.02 The Rising Son]]===[[Drexel]] says that he and the demons have been searching for Lucifer, even checking the cage, and yielding no results. ===[[14.20 Moriah]]===Castiel meets with a demon to visit the cage and study it, but she is uncooperative. When [[Chuck]] gives Sam and Dean [[The Equalizer]] to kill [[Jack]], Castiel suggests throwing him in the cage until they find a way to save Jack, but Dean, who is too stubborn to care, shoots down the idea. ===[[15.01 Back and to the Future]]===[[Belphegor]] tells Dean that every door in Hell sprang open all at once when [[God]] started the end of the world. Dean realizes that this means Lucifer's Cage as well and asks about [[Michael]]. Belphegor tells Dean that the last he heard, Michael was still just sitting in the Cage, but suggests that if Michael got out he might hold a grudge against the Winchesters. ===[[15.08 Our Father, Who Aren't in Heaven]]===After realizing that [[Michael]] might know something that could help them beat [[God]], the Winchesters and [[Castiel]] use one of [[Rowena]]'s spells to travel into Hell to talk to the [[archangel]] in the Cage. After interrupting a brawl between the three and several demons, Rowena, now the Queen of Hell, reminds them that the Cage is open and Michael could be anywhere in Hell or on Earth. However, Rowena has her demons search Hell for Michael when they impress upon her the urgency of the situation. The demons subsequently report back that Michael is gone, having escaped from both the Cage and Hell. Following his escape, Michael continues to use [[Adam Milligan]], who he took out of the Cage with him, as Michael's [[vessel]] on Earth. During their years together in the Cage, Michael and Adam were able to reach an understanding since all they had was each other and now share control of Adam's body and even appear to have developed a friendship. After being captured by the Winchesters and Castiel, Michael is angry at Sam and Castiel for their roles in trapping him in the Cage and at Dean for abandoning Adam there while letting Lucifer free upon the world. Adam, while arguing with Michael, reminds the archangel that God abandoned Michael in the Cage as proof that they are right about God. Dean later apologizes to Adam for allowing Adam to get trapped in Lucifer's Cage, stating that Adam is a good man and didn't deserve that fate.
