The Dungeon of Niflheim was currently home to 15 floors -excluding the floors 5.5 and 10.5- and all but the final floor was fully stocked with environments and expansions. However only the top ten floors were in use by the public given that no one had ever reached beyond the tenth floor -bar the team from the federation of knowledge. This was primarily due to the vast sums of C-rank monsters prowling the halls.
Furano and the nearest towns and enclaves had few C-rank parties let alone groups at the B-rank thus this was a barrier no one could overcome. Eventually if Frost left things as they were B-ranks would be attracted to the Dungeon and would destroy his current utopia with their overwhelming strength. At the moment only he, Khuno and Findley were capable of going toe to toe with a B-rank party. Though his C-rank forces were numerous, to take down a party of that level would result in some serious losses to their numbers, a price that Frost would find hard to stomach.
