In the New Tales From Middle Earth Novel:
I'm Éomer son of Éomund son of Eastfold who had married Théodyn sister of Théoden 17th King of the Mark.
Saurmen had declared himself Lord of Isengard and began to give trouble to Rohan soon after Thengel, father of Théoden returned to Rohan from living in Gondor. Éomund, who was chief Marshal of the Mark, was killed in the year 3002. He was pursing a small band of Orcs to the borders of Emyn Muil where he was surprised by a strong force which had lain in wait for him in the rocks. My mother died soon after because of her grief.
King Théoden took us into his home and called me and my younger sister Éowyn his son and daughter treating us as well as he did his son Théodred. I became a rider of the Rohirrim and Third Marshall of Riddermark. My area of service was the Eastfold which is why I was so far away from Westgard and Théodred when the Uruk-Hai breeched our boarders.
My part in the War of the Ring is well known and need not be retold at this time. Together my horse Fireheart, his horse, a dapple gray stallion and I rode as one beside our friends and comrades.
After Théoden's death I was crowned the 18th King of Rohan. King Elessar renewed to me the gift of Cirion and I took the Oath of Eorl. This allowed me to rule as king of Rohan while Elessar ruled in all theother realms of the land. I fulfilled my oath on many occasions for the evil sown by Sauron did not die with him and many years passed before the White Tree could grow in peace. Wherever King Elessar went to war so did I. The thunder of the cavalry of the Mark was heard beyond the Sea of Rhûn and on the fields of the South as the flag of the White Horse upon Green flew proudly.
In the last year of the Third Age I did wed LothÍriel, daughter of Imrahil. I ruled the Mark as well as I could for sixty-five years. Our son Elfwind the Fair ruled after me.
So say I, Éomer Éadig, Lord of the Mark
