nurufantur

masculine name. Lord of Death-cloud

A surname of Mandos as lord of the dead in Silmarillion drafts from the 1930s (LR/207). In The Etymologies it was given as a compound of nuru “death” and Fantur “Lord of Cloud”, the latter of which also appeared in the surname of his brother, Olofantur (Ety/ÑGUR, SPAN).

Conceptual Development: The first form of this name in the earliest Lost Tales was ᴱQ. Vefántur “Fantur of Death”, where the initial element ᴱQ. was another name of Mandos (LT1/76; QL/37, 100). In early Silmarillion drafts from the 1930s this became ᴹQ. Nefantur (SM/166) and finally Nurufantur (LR/207). This name disappeared from Silmarillion revisions from the 1950s-60s, but the term Q. Fëanturi was still used to collectively describe Mandos and Lórien.
