The Godly Entity Appears
From ONISM1999
The Godly Entity Appears is a song that used to play during the cut tutorial boss, and all throughout the Tutorial Dungeon during the Ultima Ending (when the internal "TheEnd" value is equal to 11). It was composed by Andrew Allanson. It's also a cover of the second movement of Debussy's Nocturnes.[1]
It was featured on the YIIK: A Postmodern RPG Official Soundtrack, but was removed for unknown reasons.
