Known as the middle brother and son of Aluin. Ranuin represented months. He appeared like an old man of middle stature and had neither long nor short hair. His brothers were Fanuin and Danuin (Year and Day) and they were all considered the children of time. Thus they were Maiarindi. They may have become Maiar of Vaire, the Weaver of Time or remained as representants of Aluin of the Timeless Halls.
