Bane

Bane was the Athelian god of tyrannical oppression, terror, and hate, known across Athelas the face of pure evil through malevolent despotism. From his dread plane of Banehold, the Black Hand acted indirectly through worshipers and other agents to achieve his ultimate plan to achieve total domination of all Faerûn.
Personality Bane was a wholly malevolent and brutal deity that distanced himself from mere mortals, preferring to reign over his followers from afar. He savoured the terror he instilled in others and the hatred that formed in mortals' hearts, utilizing this strife to gain greater control over the Realms.
Worshipers Among the evil gods, Bane's church was among the most stable and powerful. While there was a time when the god encouraged sectarianism and violent disputes, that time has long since passed and today the god's Faithful were as likely to solve their disputes through reasonable debate as through show of force. That being said, Bane's church was no less ruthless than that of Cyric or Shar and it obeyed a strict hierarchy extending from the god's most powerful worshipers to his weakest ones, with the god himself the lord of everything they did and, though worshipers of Bane came from every station in life, they all knew to whom they owed their blessings, ready to turn it over to the Black Lord at any time.
Banite customs were often quite spartan in nature and the god's followers celebrated no holidays in honour of their god, instead showing their gratitude to him through service and the ritual torture and sacrifice of sentient beings offensive to the god. Priests of Bane prayed for their spells at midnight, pledging their eternal loyalty and service to the Black Hand, knowing full well that the penalty for failure or disloyalty was death.
The church of Bane increased greatly in recent history due to his return. With this he gained nearly all the worshipers of Iyachtu Xvim, his half-demon son, as well as some of Cyric. Many of those among the god's worshipers were fighters, monks or blackguards, or wizards.
His clerics could be recognized by the black-enameled gauntlet worn on one fist. They were able to cast spells against undead, such as a flare of greenish phosphorescence which seared smaller undead or an even fiercer radiance that seared ghouls and phantoms.
