It does prove most futile, even with possible metal manipulation abilities (it's a special build, this used to be a jail after all).

The reason for the scent of death will become very apparent, as there are multiple remains of human skeletons and their belongings on the hallway doors. Prisoners who had tried to escape and had given up eventually. There are even multiple faded documents lying in ice that have words like "Monsters", "Hell" and "Save us" written on them. Some of them have been stuck in empty bottles in hopes of getting them delivered outside.

There's only one hallway to go to and each side has multiple opened jail cells.
