A person as powerful as you has unraveled many of the world’s secrets, sometimes without even trying. There are many who would do anything to learn what you know. They do not understand the unsettling consequences of revelation. Some knowledge is burdensome, and eats away at you in quiet moments.
Something common: You have learned that an ordinary household tool bears a resemblance to the agent of something sinister. What is it, and how can it be tested to ensure safety?
Something masked: There is an institution or group that ordinary folks accept as benign. However, you have discovered a fantastic purpose or origin for it. It might be harmless now, or it could still be an active conspiracy, but you know the hidden truth. What is it?
Something ubiquitous: Your journeys have taught you the true origin of something vast and ever present like the color of the sky or the shape of the moon. This truth has elements of the ancient origin myths but is most certainly different. What do you know? Does knowing it change the way you look at the world?
Something absurd: There is something that many view as miraculous, divine, or otherwise sacred. You have learned that its true nature is amusingly uninspired or insignificant. What is it? Has this knowledge caused you problems?
