Older(?) brother of Isildur and Anárion in Lord of the Rings drafts from the 1940s, this character was quickly rejected (TI/119). The name might be a compound of Ilma “Starlight” and the suffix -(n)dur “servant”, as suggested by Roman Rausch (EE/2.14).

Name for the region of Air in Silmarillion notes from the 1930s (SM/236). It is simply vista “air as substance” used as a name.
This name first appeared in Silmarillion drafts from the early 1930s as ᴹQ. Silma >> Ilma >> Ilmen as a name for the “Place of Light”, home of the stars (SM/240-1). It reappeared in the mid-30s as a word for “Starlight” (LR/205), and also appeared in The Etymologies as a derivative of ᴹ√GIL, alongside (and perhaps an element of) Ilmen “region above air where stars are” (Ety/GIL).
