Eladrin hexblade, assassin of the Hands of Fate. Killed in a training exercise.
Gadreel was a moderately talented juggler in his youth. While travelling one day, his circus troupe accidentally stumbled into the Shadowfell, where a small group of Hands of Fate agents were on a mission. The agents (uncharacteristically) took pity on the troupe and helped guide them back to the Prime Material plane. Intrigued by what he’d seen, Gadreel ran away from the circus to join up.
Three words to describe Gadreel: curious, acrobatic, occasionally inappropriate.
