It is about the attempt of Majapahit Empire to expand their influence beyond Java. King Jayanegara has been murdered by his surgeon (it is implied that Gajah Mada had some part in it) and his step sister took over the throne as queen regent and has appointed Gajah Mada to prime minister. Gajah takes his famous oath, Sumpah Palapa, not to eat any spices until Nusantara is unified under Majapahit rule.
