- Disambiguation: This is about King Óin, father of King Náin II. For the Óin of Thorin and Company, uncle of Gimli (of the Fellowship of the Ring), see Óin.
Óin's reign was largely uneventful while he and his people lived in the Grey Mountains. Into the final years of his reign, Sauron returned to Dol Guldur in Mirkwood and his shadow spread. As well, the Orcs of the Misty Mountains spread, plundering Moria and occupying it for hundreds of years.
