His upper torso is coppery brown, while his lower torso and fins are silver and scaled. Vepar\xe2\x80\x99s hair is long and black, and he usually wears it tied back or braided. His eyes, usually blue in color, burn with a silvery fire when he is angry or excited. Under his hair, two small copper horns can be seen just above his eyes. Vepar\xe2\x80\x99s hands end in wicked claws with silvery nails. \n'b' A brooding and malevolent demon, Vepar relishes in the torture and death of others, particularly mortals (whose very existence he disdains). He leads 29 battalions of shrroths in service to his master, but his loyalty to Dagon is questionable at best. Behind the scenes, Vepar is quietly amassing an army of demons to one day lead against his current lord. But for now, he waits and serves. \n'b' Vepar\xe2\x80\x99s citadel, Leviathan\xe2\x80\x99s Reach, is built into an underwater mountain range that sits several miles below the surface of his watery Abyssal home. The citadel is guarded by scores of aquatic demons, fiendish merfolk, and fiendish tritons, as well as several hundred sahuagin.'
