Light Temple (InstanceTopic, 15)
From Compile Worlds
The Light Temple is a temple of light, built and dedicated to Harpy and her ancestors. It was artificially expanded by Ecolo to include a huge, multi-floor maze with walls and floors made of glass, as well as elevators. Normally, one would need to traverse the maze to get to the Altar on the bottom floor, but when our heroes visited in Episode 50, Angol Mois simply created a portal to the room. The Puyo Spirit Serra was sealed here.
Unfortunately, the heroes couldn't just blast a giant laser through the glass as if they were Iji like usual.
