“Thousand Demon Eyes, release."
"I will return unto you your curse. Be melted down."
"Pandemonium Cetus! Fuhahahahahaha!”


Pandemonium Cetus: Forced Seal, Pandemonic Temple (強制封印・万魔神殿パンデモニウム・ケトゥス, Kyōsei Fūin - Manmajin-donoPandemoniumu Ketusu?) is the Noble Phantasm of Gorgon. By renouncing to her last vestiges as a goddess, the shadow of her former self that she becomes at the very end, and the monster that was her (original) self's origin, the “Gorgon monster/Gorgosso” is temporarily materialized and all life within the designated territory is liquefied.[1][2] It instantly robs the lives of humans, and even Servants are given severe damage.[1]

Despite being a strengthened version of “Blood Fort Andromeda”, the Noble Phantasm that Medusa possesses when she is a Rider, it does not require setup time and is invoked with just the release of its True Name. Effectiveness is somewhat low against inorganic-type opponents.[1]
