assistant
Gellert is an aging halfling, who appears older than he actually is due to the effects of countless battles. His wrinkled face is framed by long, stringy hair held back in a braid. His graying beard hangs loose below his chin. Despite his age, there is a trace of youthful vigor about him. His clothing is made up of simple, sturdy garments that match his physique. He carries a heavy warhammer in his right hand.
