Exit of the Evening Dusk

Exit of the Evening Dusk is a British Golden-style magic cabal. They were involved in the background of the events featured in Mark Space SS.

Background
At some point, the cabal started supporting oil drillings in the Arctic Ocean, in order to use the funds they gain from the drilling to buy children from a Portuguese "market" magic cabal.

Magic
Exit of the Evening Dusk are apparently very wasteful, as they would use up a lot of resources to obtain a small, non-proportionate effect. It seems that the cabal primarily uses children as materials for spiritual items. As a human’s life force is used to refine magic power, they want to refine a large amount of magic power in an instant to get an explosive reaction from a large-scale spell. According to Levinia Birdway's example, in order to create a simple charm that can conjure a few biscuits, Exit of the Evening Dusk needs to use the lives of three children. She also estimates that it takes about 0.7 seconds to shatter the minds of the children and turn them into empty shells.

Mark Space SS
While none of the cabal's members are featured in the story, they are at the root of the incident, as they support the oil drilling of the Blue Research in order to gain funds. This leads to a planned attack on the ship in order to sink it and crush their finances, and therefore makes Leivinia send Mark Space to retrieve her sister, Patricia, who is on board.
