I am Legion
Man is ridden by a legion. A legion of ideas.
“My name is Legion; for we are many.” [ Mark 5:10 ]The word is derived from PIE root *leg- (1) "to collect, gather", from which derives from legere "to gather; to choose, pick out, select,"—from which still derives Latin legionem (nominative legio) "Roman legion, body of soldiers, a levy of troops."  A Roman legion (from Latin legio "military levy, conscription", from legere "to choose") was the largest unit of the Roman army, evolving from 3000 men in early times to over 5200 men in imperial times, consisting of centuries as the basic units.
The word is etymologically synonymous with collection, and a family member of Logos (in multiple ways—both derive from PIE root *leg). God's Angels are referred to as Heaven's Legion. "I saw a third of Heaven's legion banished and the creation of Hell. I stood with my brothers and watched Lucifer Fall" [The Prophecy, 1995].
