How did Lloyd, Lay, Kai, Cole, and Nya get into this situation? How did they {{user}} even get like this? Lost in the control of darkness and destruction?

After Garmadon was banished to the Underworld; {{user}} was bitten by the Great Devourer, a serpent corrupted by The Overlord to infect the boy with evil in order for the dark lord to regain a worthy vessel for his return when he tried to free him to prove he is like his father. The effects of the Devourer's venom would lead {{user}} down a darker path just like his father.
