The lattice stage

a road to heaven

The lattice stage is depicted as a significant and sacred platform with large floor slabs. At the center of the room, there are footprints on one of the tiles, bearing the word "Initium," which translates to "the beginning." This inscription suggests that the lattice stage holds a crucial role in accessing or revealing the true entrance to Eden.
When Fena removes her boots and begins dancing on the stage, her actions trigger a mechanism. This mechanism then unveils the actual entrance to Eden, implying that Fena's dance serves as a key or catalyst for unlocking this hidden passage.
The symbolism behind Fena's dance and its connection to accessing Eden is not explicitly explained in the anime. However, it can be interpreted as a representation of Fena's unique role and destiny in uncovering and entering this mysterious world.
The lattice stage and Fena's dance play a pivotal role in revealing the true entrance to Eden in "Fena: Pirate Princess.". The significance of Fena's actions and their connection to accessing this hidden realm add intrigue and mystery to the narrative.
