The Library is a building that can be accessed in Ranhorn after beating stage 2-16. Here, players can access the Field of Stars, The Elder Tree, Gear Resonance, and Unions to grant their Heroes a variety of bonuses and receive additional rewards.


This old library is crammed with countless tales written by the travelling bards of Esperia. Within it are the stories of many great heroes, some touching, others heartbreaking. They tell the tales of how great friendships and alliances were forged, brought together to fight against a common enemy, they are forever unbreakable.
