Shar is the goddess of darkness in the Forgotten Realms campaign setting.

Being the opposite of light, she is invariably an evil deity and one of the major players of the Realms. Sure, Bane and Cyric get more screen time and are generally seen to be more diabolical, but Shar is quietly competent and probably succeeds in being the true BBEG of the setting with the subtler, long term plans.

History

Shar was created by Ao at the dawning of the material universe. In the beginning there was only Shar and her sister Selûne, who represented two opposing cosmic forces. However, since not much was going on in the empty universe and since both were fairly innocent at the time there wasn't much animosity between them.

Since Ao was a deadbeat dad who never spent any time with his kids, Shar and Selûne decided to entertain themselves by combining their forces to make things and set about crafting everything material.

They crafted the earth and called her Chauntea then went about filling it with all sorts of forces and creatures which necessitated making more gods for them to play with.

So, like any God, when they had completed their work they decided to rest and have some brewskis.

It was only when Chauntea reckoned she was a bit cold that the sisters came into major conflict. Selûne ignited a star and called it Lathander, bringing light and warmth into the universe. Unfortunately Shar was nursing such a terrible hangover from celebrating the universe's ribbon cutting that she couldn't tolerate the light and got into a mighty bad mood and demanded Selûne turn it off.

When Selûne responded that one simply doesn't turn Amaunator off, Shar got mad and threw pieces of magical darkness at her sister in an attempt to shut the light off, ripping chunks out of her, wounding Selûne badly and diminishing her from "Greater" goddess level down to "Intermediate".

However, the chunks that were ripped off commingled the opposing forces of light and dark and created something entirely new: Mystryl: Goddess of magic.
