Lord Fell

One of three stormlord vassals — with Grandison and Cafferen — who marshalled for Aerys against their own liege. Robert refused to let them combine, marched hard, and broke all three hosts separately at the ruined palace of Summerhall in a single day.

Lord Fell died there, killed by Robert in single combat. His famous son was taken captive in the same battle and afterwards won over entirely, which is the pattern of Robert's whole war in miniature: kill the man in front of you, then feast his heir.
