The «Hill of Memories» is a field dungeon located in the northern region of the floor and is the place where Beast Tamers who have lost their Tamed Monster may come to find a Pneuma Flower to revive their fallen pets.
The floor was reached and cleared sometime around November or December 2023. Later, on February 24, 2024; Kirito and Silica came to this floor in search of the Pneuma Flower. After navigating through the Hill of Memories, the duo reached the end of the dungeon where they acquire the pet revival item. On their way back, they were ambushed by members of the Titan's Hand guild, which attempted attacking the duo for the flower. However, Kirito was too powerful for them and threatened to paralyze them with a paralysis poison if they did not surrender, before teleporting them to jail. All the members except Rosalia entered the corridor to the prison in the Black Iron Palace, while Rosalia was forcefully thrown in by Kirito.
