TEGANA: I will use it well...on all but the first of Marco Polo's water gourds, for tomorrow, the caravan sets out to cross the Gobi Desert. Now, you will follow us...and on the third night, I will walk back to you...then we're gonna ride back here to Lop, wait for two days...and then...return to the caravan...to collect the...thing of magic...that will bring the mighty Kublai Khan to his knees!
