Corridor of Blood (Japanese: 血の回廊, "Chi no Kairō" / lit. "Corridor of Blood") are passageways connecting several of the back-side fields of Eg-Lana. Each entryway to the corridors have a six-pointed star above it. A bar within the star shows how the corridor will connect with other fields. The orientation of the bar (the angle at which it's tilted) shows how the corridor will be tilted when you enter it, but the field to which the corridor connects is not immediately obvious from the door.
To rotate the Corridor of Blood, you must use the Beherit in front of a door leading to the Corridor of Blood.
The six-pointed star arrangement above the door is a clue: the connections between the corridors can be conceptualized as if each of the fields was one of the points of a six-sided star. The bar, then, shows to which another point on the star of fields the corridor currently connects.
Reaching the Eternal Prison
- Location: Any of the entrances.
- Use the Djed Pillar to chant Sol, Mani, and Saer together.
- Be warned: Once you enter, you cannot leave with the Holy Grail, and the entrance is one-way only.
Activating the Spiral of Life (Mild Spoilers)
After getting all 6 Dissonance, use the Beherit in front of all of the Corridor of Blood doors until they shoot out a red laser. Follow the path for all 6 of them, and a cutscene will play, activating the Spiral of Life on the Spiral Boat at Immortal Battlefield (E-4).Be duly warned that this will render the Corridor of Blood completely inaccessible for the rest of the game. In addition to locking off the shortcuts from area to area, this can render the Glossary ROMs and Brahma's Trials uncompletable on that file. It is strongly advised that one makes a separate save before sealing off the Corridor, in case there are any items that they are missing.
