Enter Gato Grottoes.
Go to the Dreamweaving. Depending on who you chose to side with in the previous Events you will need to have that person join your party. After the scene, talk to the person you sided with (I chose Daena) to have them join and then talk to Matilda to get the Brooch of Love AF.
Place the Brooch of Love AF in the space directly to the Right of the Jungle to create Lucemia. Enter Lucemia.
Head to area 30 on the map of Lucemia to get to Irwin.
Defeat Irwin to end the final Event with Escad and company.
Return home, talk to Lil' Cactus, go downstairs (watch him write the Event on the leaf), and go back upstairs to save your game before continuing.
