During a side quest over the course of the game where the Brave Vesperia guild takes on several jobs, the player will be given a manual belonging to the prisoner Irmine, which must be delivered to Nobis of the Soul Smiths guild and is a requirement for unlocking a special weapon. As you continue further in the story, traveling to Aspio after Spoiler:Nordopolica is attacked will trigger a scene where Rita talks to her fellow mages about Spoiler:Spirit conversion. After rebirthing all four Spirits and unlocking Tarqaron, the last dungeon in the game, a new scene can be triggered by going to Halare, at which point you must go finish the guild job side quest and return to the tree in Halare. Another scene is triggered where the Soul Smiths reveal they have crafted a unique blade and gift it to Rita. This is a whip called the Ivy Blade, and it's based on the primary weapon used by Ivy Valentine in the SoulCalibur series.
