The artifact known as Paradox is known to have been discovered by Ruttledge, Kaminski, Parzen, and Lu-lan, but may have been discovered many times before. The interior of Paradox contains a powerful lotus field, which erases all memory of any biological or electronic device entering the field. Ruttledge and Kaminski were discovered by Parzen and Lu-lan a few days after entering malnourished and with the mental ability of a newborn infant. Lu-lan and Parzen chose to confirm what happened by sending in one more person. After drawing lots, Lu-lan returned after three days with his memory completely empty, though his knowledge was intact. Paradox has since been declared off limits to all but specially trained investigators.
