ALT The Triangle Agency Normal Briefcase Collection all together: Rulebook, The Vault: Missions for Triangle Agency, The Triangle Agenda, six four-sided dice, and the Normal Box. The Triangle Agency cover features a figure in a casual business suit walking away with a briefcase that's shining with magic red light. The Vault cover shows a strange door in the shape of a petrified, snake-like creature. The Triangle Agenda cover looks like a strange tunnel of marbled red light ending in a glowing triangle. The box looks like the briefcase from the Triangle Agency cover, but torn with use and covered in stickers.
