|Title(s)||The Blooded Baron|
|Power Level||Demon lord|
Arzial is a cambion, born of the demon prince Graz'zt and a presumably human woman. The least accomplished of Graz'zt's many children, Arzial still has a vital role in Graz'zt's schemes.
Arzial's father is Graz'zt, making him the half-brother of Athux, Belyara, Iuz, Rule-of-Three, and Thraxxia and the grandson of Pale Night. He has a close relationship with a female wizard known as Demara the Enchantress, whose half-fiendish son MacDaer Arzial fostered for fifty years, teaching him magic and the ways of the Abyss. The exact relationship between Demara, Arzial, and MacDaer is unclear; Arzial could be MacDaer's father, brother, or no true relation at all.
Vulderpayne is remote, but still important to Graz'zt. It is located in Pazunia, the Plain of Infinite Portals, a harsh realm of iron fortresses and deep pits that act as portals leading to the lower planes of the Abyss. Fiendish Codex I actually says that Arzial's barony is within Graz'zt's realm of Azzagrat, while the Demonomicon of Iggwilv article by James Jacobs placed it in Pazunia. Perhaps Vulderpayne contains a portal to Azzagrat, which would explain Graz'zt's desire to keep it under his control.
