Portal from Kurobano to Akakura

Every fourteen days a gate can be opened from the Fudo shrine of Kurobano to the holy fire on the cliff near Akakura. The key is the ring-song of the seven fire stones. When the song reaches the passage praising the Five Angry Gods of Light and starts describing Fudo’s power of passage between the worlds, the barrier between the material plane and Celestia weakens and the portal opens.

This is a one-way portal.

See Portal from Akakura to Kurobano for ways back.

This portal does not require you to wade through waist-deep holy water. Knowledge of this portal would thus be of great value to agents of evil. Unfortunately it requires enslaving or tricking the priests of the temple in Kurobano, for without the song, the portal cannot be opened.
