When Ainz attempted to contact Albedo after deciding to head to the Elf Country, he learned that at the time she was in the prison.[5]

After Mare Bello Fiore successfully defeated Antilene Heran Fouche and took her prisoner he informed his master Ainz Ooal Gown of the woman’s possible link to Shalltear’s brainwashing. Ainz then transported his party from the Elven Royal Castle back to the Log Cabin so that Aura could carry the prisoner to the Frozen Prison so she could be interrogated by Neuronist. Having been warned about the woman’s formidable strength, Ainz assigned Mare to stand guard with Neuronist.[6]

Afterwards Ainz was present in the interrogation room where Antilene was caged before Neuronist, and the dark elf twins. It was there he learned that the Slane Theocracy was indeed responsible for brainwashing Shalltear, causing him to summon Albedo to inform her that the Sorcerer Kingdom was declaring war on the human nation.[7]

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.

  • Room of Nigredo: The cell where Nigredo, Overseer Guardian Albedo's sister, is kept in confinement. The entrance to her chamber is disguised as a painting of a mother cuddling her baby.
  • Room of Truth (Pain is not to tell): Neuronist Painkill's personal place of office. In other words, where Neuronist and her Torturers process freshly caught captives for interrogation. It's filled with a number of horrendous torture contraptions and equipment.
