After they finished their rest and were ready to move on to the next floor, before going down the stairs, Shingi started drawing a special Enchantment on the footwear of everyone.
The same Enchantment Varic had drawn to Ameanum's boots when he went to meet with Lucy.
The next level would not follow the desert theme but instead was a water level.
The entire floor would be a vast ocean with islands of different sizes, but none would be large enough to hold over fifty people, while the smallest ones could barely hold two.
When a group moved to that level, they could start at any point on the floor, including at a place with no land.
