Dwimordene derives from Old English, representing the name of this land in the tongue of the Northmen. It contains dwimor 'phantom, apparition', and dene 'vale' (presumably referring to the valley of the river Silverlode). The combined meaning, 'vale of phantoms', gives some insight into how the Northmen viewed the mysterious beings - from their perspective - who inhabited the Golden Wood. They also used dwimor, without apparent distinction, for the Dead who walked the Paths of the Dead beneath the Dwimorberg (or 'Haunted Mountain') and for the Ringwraiths (whose Lord was named dwimmerlaik by Éowyn).
