The area known as Acid Aerie is a large cavern to the northwest of
Blingdenstone and Menzoberranzan located in the Underdark wilderness. Due to
either some natural phenomenon or a runaway spell, the cavern has been slowly
melting as volumes of acid eat away at the cavern walls. A large number of
dire corbies, a cruel humanoid bird native to the Underdark, have found the
region to be a suitable nesting ground, though they make the area difficult
for any travellers nearby.
* This is a training area for Underdark races first, before those from the
surface.
