Entwash

Entwash appears in The Lord of the Rings.

The Entwash, the mighty river born from the union of the limpid Entwash and the boisterous Onodló in Fangorn Forest, serves as a vital geographical feature shaping the landscapes of Rohan and the Anduin Vale across The Lord of the Rings. Though not prominently featured in narrative events, it evolves from an unnamed waterway in earlier tales to a named boundary in the appendices, underscoring its role in the series' intricate world-building. Its steady flow carries the essence of the Ents' wrath southward, paralleling the awakening of ancient forces against the Shadow.
