The Seafloor Palace is a new location in Kid Icarus: Uprising, and is supposedly the home to Thanatos. As its name suggests, this legendary structure is hidden deep underwater, accessible by a magical pathway located beneath the waves that only the god Poseidon can reveal. When traversing it, Pit will have to fly very close to the ground and even be able to run extensively while avoiding numerous rocks that litter the seabed, in addition to Medusa's aquatic forces.
Thanatos's high-security fortress at the bottom of the sea. It's connected to the Underworld, allowing forces to be sent to the surface via bubble transport. Poseidon helps Pit infiltrate the Seafloor Palace by parting the ocean.
