Gol Garga

Gol Garga was the mastermind and supreme commander of the massive orcish invasions of southern Orithea which lasted from 1231 to 1253 CV, ending just two years before the present day. He is widely considered the greatest and most dangerous orc warlord in recorded history, and many believe that his hordes would have continued their rampage northwards and eastwards if he had not mysteriously disappeared on the eve of the decisive Battle of Crow’s Gorge. 
Whether he is alive or dead, none can say with certainty; a thousand rumors circulate and countless sightings of him have been claimed since his disappearance, but of course that is to be expected of any infamous figure who suddenly goes missing. None of these rumors have been born out, none of the alleged sightings confirmed. His fate remains an enigma.
