Arien is a small village in Andor, on the road from Whitebridge to Caemlyn. Mat and Rand stay there overnight. The innkeeper tries to talk them into staying an extra day, and unlike most places they have been, the patrons do not seem concerned by Mat's suspicious looks and behavior.
Eazil Forney is from Arien.
