The Severed Union was particularly brutal.
As an organisation that existed mainly to keep track of the world's nastiest potential disasters born from either extremely powerful Clusters that spawned away from the mainland; sentient magical weapons that could threaten civilizations; obscene natural disasters bolstered by the world's magical nature, and more, it was imperative for it to have a core circle.
The possibility of all the Factions being wiped out in one dangerous incident was extremely high, especially with an assignment of the calibre of the one all the current Factions were currently participating in.
An assignment with the sole objective of capturing and killing the masked man before he reached Edagon to achieve his goal.
