That much is obvious. [To the first part, about the fog twisting the mind. Sometimes, others flicker in the corners of Rei's vision, paranoid delusions of people who want him dead and not merely "that annoying nuisance that is Kuya".] There's minimal ambient Essence in the air here. I've never encountered anything quite like it. Even the Dead Zone feels ominous in its emptiness. This place feels far too quiet.

[In a good way! Until they find out this place gets regularly attacked, anyway, but right now it's quiet in a good way. In a "this place might be abandoned" way, until he spots the distant figures of others flitting about in the distance. Hm.]
