Blade of the Equalizer

Blade of the Equalizer is one of the three parts needed to construct the The Equalizer. This part can be found in the Mind Flayer's Dungeon, at one one of the tables near your cell.

In-game description
"This is a part of the Equalizer, a great long sword forged long ago as a tool for balancing the powers of the universe. Also known as the 'sword of neutrality', it did greater damage the further the target's alignment was from True Neutral. The Equalizer was last rumored to have been wielded by the elven hero Alaine Greenleaf, who was lost during a voyage to the Underdark. Other rumors have, however, proposed that the blade's pommel gem was stolen by an escaped slave who returned to the surface world."
