Formennen

After Twyferry, river Entwash divided and the branch to the north was called the Formennin (S. “North Channel“). It skinned the north edge of the Medennin (S. “Wet-vale- waters"), the so-called Midden, a marshy swamp fonned where the Ennhir (S. “Middle Stream") broke away from the southernmost channel, by common consent thought to be the Onodló proper.
