Wiaterna is a town and port in former Emblonia, located upon the backwater of the Pontar River. River travel from Wiaterna to Novigrad takes about 3 – 4 days. Sylvan Dam is located about an hour's brisk walk from here.

In 1245, Geralt passed through here with Addarion Bach to seek out a boat ride to Novigrad and were offered room on the Prophet Lebioda, but with strings attached.
