Second trip of the polos

The three Venetians set out for Ayas with a letter from the Cardinal Legate to the Great Khan, confirming the honest efforts of the Polos to fulfill their mandates and justifying their partial failure with the continuing vacancy . On the way they find out that the legate has meanwhile been elected Pope as Gregory X. on September 1st and travel back to Acre at his request.
