Q. Pelóri Valion loc. “Mountains of Valinor”
A longer name for the Pelóri mountains, with the descriptor Valion “of the Valar”, the (archaic?) genitive plural form of Vala (MR/18). In one place, Tolkien changed this name to Pelóre Valion (MR/33), but since Pelóri consistently appeared in plural form elsewhere, this is probably an aberration.
