>>21592606In the original PC-98 version, the final dungeon design is a reference to the Black Lodge from Twin Peaks, which appears first in this part:
>Ayato enters Ohanayashiki in Asakusa. After defeating many Japanese yokai demons, Yoshino-Hime brings Ayato to his spiritual world, where Ayato sees his past and a few scenes of the future. In the spiritual world, Ayato finds out that Watanabe was killed by Baal Hadad, who later disguised himself as Watanabe to manipulate Pentagramma. Furthermore, Yuuka tells Ayato to revive Goshiki Fudo, and Baal calles Ayato his son. Before exiting spiritual world, Ayato defeats his own shadow, Doppelganger. Yoshino-Hime tells Ayato that Tokyo's fate is in his hands nowIn other words, the final dungeon takes place in Ayato's own mind with him facing another piece of Bael like him, Murmur (who comes from the Sumerian Mummu, the vizier of Abzu, the primordial waters of the Sumerian Ogdoad represented as aquatic blue liminal space with crosses and winged serpents at the doors in Windows version), before face Baal himself.
>Mummu (Cuneiform: 𒀭𒈬𒌝𒈬, dmu-um-mu;[2] logographically 𒀭𒌣, dDÉ[3]) was a Mesopotamian god. His name is presumed to be derived from the Akkadian word mummu, "creative force". Mummu is best known from the epic poem Enūma Eliš, where he is portrayed as a servant of Apsu (uncommonly treated as a personified deity rather than a supernatural body of water) defeated alongside his master by Ea. Attestations from outside Enūma Eliš are known too, though they are comparatively uncommon >Mummu is a craftsman, the personification of practical knowledge and technical skill. As the third of the primordial gods, Mummu is said to symbolize the mental world, the Logos, according to the Neo-Platonist Damascius. Franz Böhl arrived at this association as well, deriving mummu as a participle of the root "to speak" and calling it a precursor of the Hellenistic Logos, although Heidel disputed this etymology
