Into one of the mountains nearby is carved an enormous
system of sewers. No one is certain why they are - there is no evidence
that the Empyrean built a city in this area. Perhaps they are of
pre-Empyrean vintage. To reach them, follow the road southwest to
our outpost. Then, head west into the hills. You will see the entrance
to your right, nestled in a ledge on the side of the mountain. It
is said that some have found habitable areas in the depths.
