Sauron overruns Eriador
Event Type: Military/Strategic
Age: 2nd Age - Rings
"But now Sauron attempted to gain the mastery of Eriador: Lórinand could wait. But as he ravaged the lands, slaying or drawing off all the small groups of Men and hunting the remaining Elves, many fled to swell Elrond's host to the northward. Now Sauron's immediate purpose was to take Lindon, where he believed that he had the most chance of seizing one, or more, of the Three Rings; and he called in therefore his scattered forces and marched west towards the land of Gil-galad, ravaging as he went."
