In an unmarked cabin in Wales, there is a trap door to be found under a coffee table. In this trap door, there is a concrete staircase leading down to a locked metal door. Behind this door is a 25x25 meter concrete room, filled with small square patches of dirt in concrete boxes, over these boxes there lay planks of wood with a 20cm diameter hole cut into the, these planks are 6 feet long and 3 feet wide and lay over the boxes of dirt, they have enough room for a person to lay on the plank with their back exposed to the dirt in the box through the hole in the wood. This concrete room has layers of runes carved into the perimeter forbidding all magic travel - even my own - and reinforcing the room so much so that a nuke could be dropped inside the room and the blast wouldn’t escape the confines of the basement. It was the perfect concrete tomb for these animals.
