Marco Polo's Cryptic Parchment (TARDIS Key Parchment)
A cryptic parchment that Marco Polo thrusts into the Doctor's hands during a frantic palace corridor clash and later clutches in the throne room chaos following Tegana's suicide. The parchment is wrapped around or contains the TARDIS keys, marking a pivotal handoff amid shouts and tension. Marco, with his doubts shattered, passes it hurriedly to the Doctor, urging him and Susan to seize it and flee in the TARDIS before Noghai's forces arrive. The Doctor accepts the parchment, securing their escape from 13th-century China as Polo faces the Khan's stunned guards.
