Interesting. I believe we're in the phase of the history of units surrounding the Six Heroes now. The "History of the Sama Kingdom" batch has units relative to Lucina, Selena's best friend, as well as the Sama Navy(possibly); The "History of the La Veda Republic" batch could be units relating to the school of La Veda Fencing or maybe the knighthood Atro belonged to along with Will and Aem. It's a small possible chance Will might be revived as well, The first unit to wield all Nine Sacred Treasures since Quartz split them up.
