Saturn (InstanceTopic, 17)
From Compile Worlds
Saturn is the home world of Lagnus the Brave. Not much at all is known about it, other than that it's people pray to Eldora as the goddess of faith. The Youggs destroy it at the beginning of Madou Monogatari, and it is never seen or heard of again. Subsequently, it will only feature in MPFW to reprise it's role of destruction, thus prompting the Planetary Gods of Gaias to create the Puyo Spirits and prevent a similar incident in the future.
Etymology
Saturn is named after the only game it was featured in, as well as the console the game was featured on. Coincidentally, there also happens to be a real celestial body named Saturn.
