Head to the Imperial Museum / Defeat the Dark Dragon

Once you’ve finished up your lunch, head into the Imperial Museum (Leica District) to view a cutscene, then go over to the glowing object in the room ahead. After you’re done investigating, go down into the Museum’s Basement to find the Heimdallr Catacombs. Here you’ll want to go further down and take out the three enemies, then after the cutscene you’ll want to split everyone into the following groups.

Team A Team B Team C
Juna (Leader) Sara (Leader) Rean (Leader)
Kurt Jusis Laura
Millium Fie Alisa
Elliot Musse Emma
Gaius (Sub) Ash (Sub) Machias (Sub)
Altina (Sub)

Warning!: Before continuing further into the dungeon, head back into Heimdallr Catacombs to find a Chest that contains the Magius Quartz, this increases magic attacks when your HP is low.
