The Silverfish River is the middle of the three main rivers flowing through the Nibenay Basin into Niben Bay (map).
The Ayleid ruin Nenalata and the Cadlew Chapel can be found at the mouth of the river. Going farther east, the Imperial Bridge Inn and the magical Lover Stone borders the river's shore. Peryite's Shrine is located on the south bank, next to a bridge about where the Silverfish begins to turn to the north. Fort Entius and the Ayleid ruin Ondo can be found following the river north.
