Background

Layout & Features
The Frozen Prison resembles a fairy-tale castle but the interior is anything but magical. Various wraiths and undead lie in wait, hidden from seeing eyes to launch themselves at trespassers. Located in the fifth floor of Nazarick where the entire terrain is a frozen wasteland, escape from this stronghold is impossible.
