Where To Get This Card: Card Pack 4


"It's easy for the Janus to keep their spy work secret. They don't have to worry about locking documents in hidden cabinets, or storing information on password-protected computers. When Cora Wizard learned that there could be a Tomas Clue at the bottom of the Mariana Trench, she ordered agents to create an image for the mission briefing-visual aids that looked like art to keep the Tomas from growing suspicious. Now, the only problem is figuring out how to get down there. The trench is the deepest spot in the ocean--35,814 feet. If you stacked 24 Empire State Buildings on top of each other and placed them at the bottom, the top spire still wouldn't reach the surface."


This card, when combined with Card 235 and Card 243, forms the Clue Quartz.
