Yithril

"The people of Yithril are those who the armies of mankind call Trogs, a name said to have come from the first of their kind, D'rog, who slew the last descendants of Ereog in the great battle at Engar's plain. The Trogs, or D'rog, are warriors; violence and butchery is to them what milk and honey are to other races."
