Serpent (The Banner Saga)

The Serpent is the mysterious creature of enormous size who acts as the main antagonist of The Banner Saga trilogy.

History
The serpent was an apocalyptic beast created in secret by the jealous god who responsible to create Dredge (the trilogy's primary antagonistic race) through corrupting humans as means to eradicate all life made by his nemesis Loom-Mother, the creator of life, out of envy. Its egg form was kept within the Dark Sun in the Underworld where it will grow until the time it ultimately hatch to consume and destroy the world into nothingness. During that time, the same god declared war on Loom-Mother by having Dredges wreaking havoc and attacking other creations both to spite her and kept her and the rest of the gods oblivious with the serpent's existence. The jealous god's actions led to a confrontation between him and Loom-Mother which culminated to her unintentionally killed him in rage, causing panic that resulted all gods destroying each other, something the jealous god anticipated as with all gods gone, nothing can stop his plan.

Even so, the serpent ended up prematurely born due to the energy of the Dark Sun drained by Eyvind to resurrect Juno, resulting it to fell and released the serpent and the darkness (the aspect of the serpent's power) as separate entities: The darkness caused the sun to stop and slowly consume the world, whereas the serpent became the mortal beast who struggled to retake the darkness into itself where to do that, it must consume the one who stole its powers. Ultimately, it later learned that its missing powers was in Juno's possession and began to stalk on her.

The serpent made its presence known to everyone in the world during the Dredge siege of the Varl stronghold of Einartoft, frightened everyone who present before left without any conflict. The serpent then speak to Juno in dream-world where during their confrontation, it explained its original purpose to destroy the world, but frustrated that the darkness did so in its place. On the next encounter, it tried to devour Juno for another confrontation, only for her severely wounded it with her powers. When Iver, Juno, and Eywind's caravan transverse through the Darkness in order to stop its spread from within, the serpent confronted them again, only to be confronted by Juno with help of her mind-controlled giant tentacled monster born from the darkness' corruption. The battle ends in stalmate, as it was forced to retreat with Juno severely wounded, only to be miraculously regenerated to full health.

The serpent then returned for Iver's caravan where it proposed a deal with Eywind where should it allowed to reclaim its stolen power, it will only consume the darkness and the warp it spread where the remaining parts of the world would be spared. Depending on the player's decision, the serpent would either retake its stolen power and consume half of the world along with the warp and the darkness, destroyed by the reformed black sun, or reduced the entire world into nothingness.
