Perpetual Icebox

From Mizahar Lore

This is a normal upright metal insulated chest that holds standard blocks of ice. However, once a block of ice is placed in it, the ice will never melt and will instead keep the items stored within the chest at cool and frozen temperatures depending on how far away from the block of ice the items inside the box are stored. Directly on the ice? They will freeze. On shelves lofted above the ice? They will be kept cool.
