The Coalition (sometimes the Five Torches) is the unofficial name (officially, it doesn’t exist) of the illicit and covert multinational conspiracy within many intelligence services and the Vatican to hunt vampires.
It is the most salient iteration and frequent "tip of the spear" of what Kindred call the Second Inquisition, to the point that many vampires use the term "Second Inquisition" interchangeably to refer to the Coalition and the vague movement accompanying it. If any concrete group or hierarchy could claim the exclusive title of "Inquisition" in the modern nights, it would be this.
