Arcanoloth

Arcanaloths appear as 6 ft (1.8 m) tall humanoids with the heads of fanged jackals or war dogs. They keep themselves well groomed and dressed in immaculate robes, but often wear disgruntled expressions. Arcanaloths are a relatively civilized breed of yugoloth, possessing both keen minds and silvered tongues. They're business minded and somewhat surly, but were generally truthful and had expertise in manipulation and diplomacy.
