Dagnir Glaurunga
From Tolkien Gateway
"Dagnir Glaurunga" was the title inscribed on the tall grey stone that marked Túrin's burial mound by Cabed Naeramarth above the swirling waters of the Taeglin River. Carved in the Runes of Doriath, they commemorated his heroic slaying of the dragon Glaurung — Dagnir Glaurunga means "Glaurung's Bane".[1]
