Seven Catastrophes

are a group of otherworldly beings recruited by Lillia currently aiming to destroy the world. They were introduced in The Seven Deadly Sins: Grand Cross and serve as the main protagonists of the game original story arc Catastrophe: Sacrifice.

Background
After the events that resulted on Lillia's defeat by the hands of The Seven Deadly Sins, the mage kept vainly struggling on controlling her Awakened Form. Weakened and being hunt by the Holy Knights, Lillia realizes she wouldn't be capable to achieve her dream of destroying the world by herself and starts seeking for sacrifices in order to summon allies from other worlds.

After various unsuccessful summoning spells, Lillia manages to recruit Valenti, a weapon researcher once trapped in a laboratory forced to develop weapons. The two becomes the founding members of their newly entitled group 'The Seven Catastrophes'.

Much later, Lillia and Valenti's combined efforts at the caves of Balleno resulted on Eastin Amabyllis' summoning and later alignment to the team, a nobless from another world seeking revenge for her family's demise.

Later, a failed attempt to steal old manuscripts from the Black Magic Hall that resulted in Lillia getting kidnapped by Merlin forced Eastin and Valenti to summon a new ally capable to free the mage from her space-time prison, the summoning magic brought Mono, an artificial human being created for the sole purpose of killing and following orders, who agreed on joining the team after Valenti proposed her to find a new purpose on life as her own person.

With the manuscript on her hands, Lillia manages to settle the group at the Timespace Junction, a connecting point between dimensions where the space-time fabric can be easily distorted. From there, she is capable of summoning the remaining members of the group, Roxy, a former warrior slave which agreed on helping the team in exchange of food and a place to sleep, Shin, an interdimensional robber born on an apocalyptic world, and Camila, a goddess of the Beastmen seeking for revenge against humanity.
