Princes of the Apocalypse
Sighing Valley is actually a wide canyon consisting of a deep gorge through which a small river flows. Rock spires rise from the canyon floor, and when the wind blows past these natural structures it makes a sighing—and sometimes a howling—sound.
Fauna. Wild goats are common in the canyon.
Fog. At night, fog fills the canyon, limiting visibility to 100 feet. Beyond that range, creatures and objects areheavily obscured.
Light. The canyon is brightly lit during the day, and light varies at night from dim to dark.
Walls. The canyon walls are 200 to 400 feet high.
