Leira

Leira (pronounced: ˈlɛərɑ / LAIR-ah), also known as The Lady of Deception or The Lady of the Mists, was the goddess of deception and illusions and patroness of illusionists and liars.

Months after the Avatar Crisis, Leira was slain by the new deity of death, Cyric, at the village Blackfeather Bridge, wielding the sword Godsbane, which was in fact an avatar of Mask. Her portfolios were subsequently absorbed by the mad god.

Upon her death, her godly power erupted in a blast that reached her places of worship all across Faerûn. Motes of her divinity coalesced into incorporeal beings known as glamours.

Some still believed Leira was alive and that she had used her death as a grand illusion, but the general consensus was that she was a dead power. Leiran traditionalists on Nimbral who believed her to be alive in fact gained spells from Cyric.
