Bane, also known as the Black Hand, is a major villainous deity from the Dungeons & Dragons world of Forgotten Realms. The lawful evil god of tyranny, oppression and hatred in Faerun. He used to be a mortal human fighter before ascending to godhood.
Watching from his personal plane of Banehold, Bane spreads his influence on the world of Toril through the actions of his clerics and cultists. His goal is to turn every mortal humanoid on Toril into his brainwashed slave.
Bane was a wholly malevolent, cunning, manipulative and brutal deity that distanced himself from mere mortals, preferring to command his followers from the safety of his interdimensional home. He savored the terror he instilled in others and the hatred that formed in mortals' hearts, utilizing this strife and warfare to gain greater control over the Realms.
When confronted with a potential battle, Bane would possess an individual and force their body to take on a twisted and monstrous form with leathery black skin and powerful claws that could rend flesh and metal alike. He gained any powers they held in their life, and protected his host from mind control spells.
Like many of the younger gods, Bane was once a mortal human. Little was known about the Black Hand's past as a fighter, not even precisely when it was he lived, but the evil adventurer became known when he forged an alliance with two other villains: Bhaal ( who became god of Murder) and Myrkul (who became god of death). Together, the three forged a pact of mutual aid and ambition: together they would conquer not just the mortal world, but the heavens, becoming gods unto themselves. They targeted specifically the powerful god of death, Jergal, who was among the most powerful of Toril's deities at the time.
The team, known as the Dead Three, soon became well-known to Jergal, surmounting every obstacle thrown at them. They obtained magical power and even destroyed a primordial in the Year of Sycophants. They served as generals to a great army comprising forces from three human nations, monstruos humanoids, and other races , slaying Maram of the Great Spear at the Monument of the Ancients in the Frozen Forest, taking the fallen primordial's essence, and dividing it up equally amongst themselves. Unbeknown to them, this was all Jergal's plan, for the god had grown tired of his crown, even allowing powerful magic weapons, gifted to Bane, to fall into the hands of the evil party.
When the time came to confront Jergal, the god of death tricked the Dead Three into turning on one another, each desiring the others' power. Jergal then intervened and proposed to divide up his portfolio for them, based upon a game of knucklebones, which Bane promptly won. Bane claimed for his prize governance over the sphere of tyranny, believing he would be able to rule over all of Toril in this way. As it turned out, however, Bane would not only have to be a rival to Bhaal and Myrkul, who became powerful gods in of themselves, but with the good gods as well, who would become his most hated foes.
