Cross the river to Bangkok's Temple of Dawn and uncover the story hidden in its spires. Ana, your guide since the first fragment of this tale was found, will lead you through six landmarks — a soaring central prang, giant guardians, an elephant with three heads, mosaics made from an old ship's cargo, and a hall where the walls themselves speak. Every landmark you crack open leaves you a keepsake and a clue toward the next. Piece together six letters, and unlock the name of the king who began it all.
