Who is Lilith in Supernatural?

Lilith, an eminent demonic entity with striking white eyes, was the inaugural creation of Lucifer, as depicted in the fantasy TV series, Supernatural.

Lilith played a pivotal role as the ultimate catalyst in the sequence of the 66 Seals, whose rupture was required for the liberation of Lucifer from his confinements. Initially confined within the depths of Hell, she managed to orchestrate her escape in May 2007, effortlessly vanquishing rival demons to assert her dominance, subsequently assuming the vacant leadership position left behind by the deceased Azazel.

As the commander of this formidable demonic army, Lilith spearheaded their earthly endeavors while simultaneously coordinating the diabolical forces of Hell in the War of the Seals, contending against the celestial Host of Heaven. Her profound impact became evident in 2008, as she methodically dismantled the sixty-six seals guarding Lucifer's prison, ultimately culminating in her fateful decision to permit Sam Winchester to end her existence, consequently granting Lucifer his long-awaited liberation in 2009.

Within the hierarchical structure of Hell, Lilith, as the original demon, occupied the highest echelon, surpassing the likes of Alastair, The Knights of Hell, Cain, and the Princes of Hell, second only to the commanding presence of Lucifer himself.

Who helped Winchesters against Lilith?

The weighty repercussions of her death were conveyed to Dean through the angelic messenger Castiel. United in purpose, Dean and Castiel embarked on a mission to locate Sam, urgently warning him against eliminating Lilith. However, their efforts were met with obstacles imposed by the archangels.

Castiel, commonly referred to as Cas, is a formidable celestial being hailing from the divine realm, entrusted with the profound duty of rescuing Dean Winchester from Hell under the explicit directive of the archangels. His sacred mission entailed safeguarding the integrity of the 66 Seals, whose breach would unleash the malevolent presence of Lucifer from his infernal confinement.

Upon discovering the nefarious intentions of his angelic kin to liberate Lucifer despite the consequences, Castiel valiantly rebelled against his celestial brethren, ultimately sacrificing his existence in a valiant endeavor to assist Dean in thwarting Sam Winchester's ill-fated act of shattering the final seal.

How was the last seal broken?

Lilith orchestrated the unraveling of 66 seals, strategically paving the way for the eventual release of Lucifer. As the final seal that demanded breaching, she sought refuge at St. Mary's Convent, accompanied by her loyal minions, meticulously preparing for the imminent confrontation that would lead to her demise.

Eventually, Sam, accompanied by Ruby, arrived at the scene to execute Lilith. Engaged in a formidable struggle, Sam overpowered her, employing telekinetic force to immobilize her against an altar. Astonishingly, despite the intensity of Sam's initial attempts to end her existence, Lilith somehow persevered, defying his augmented strength derived from his substantial consumption of demon blood.

It was at this critical juncture that Dean, acting independently upon Castiel's instructions, made a solitary entrance to the convent. As Dean's voice resonated through the air, Lilith seized the opportunity to mock Sam, deriding his transformation into a monstrous being solely for the purpose of eliminating her, yet now witnessing his hesitation. Lilith deemed this hesitation "adorable," baiting Sam to unleash his full power upon her.

Succumbing to the provocation, Sam unleashed his unrestrained might, culminating in Lilith's swift demise and consequently shattering the ultimate seal. Lifeless, her vessel collapsed while crimson droplets trickled from her mouth. Astonishingly, this blood commenced a spontaneous movement, converging to form a symbolic mark upon the convent floor, signaling the rise of Lucifer from his confinements within the Cage.
