This small passageway is both shortcut and hiding spot for followers of
Ithrilis.  It is protected by large, intimidating glyphs, and could be used
as a safe place in case of religious war.  A light, unnatural mist floats
through the air.  This room is clearly not given the decorative priority as
the rest of the shrine, though.  Marble walls turn to stone, and stone
floors become dirt.  It is a resting place, but not a very good one.
