J.A. Jaken's Adventures in Writing

A long, windowless corridor leads into the royal sanctuary. The corridor's entrance is next to a walled-up gateway that originally led directly into the courtyard of the royal residence. The corridor itself is kept deliberately unlit, to recreate the circumstances under which captives were led here before being enslaved. Just walk toward the light at the end of the corridor to reach your destination.

[Translator's note: A chase takes place in that corridor during Death Mask.]
