"The Horas daggar is an ancient and powerful weapon, it is said to have great magical powers that rivals that of the Sword of Plundarr.
The daggar was first crafted back in ancient egypt by an evil sorsorer who infused the weapon with magical powers of the most evil kind, then gave it to his Pharoah who then became unconqueable and mad with power.
It eventually destroyed him, the power was to much for him to handle, the daggar was never seen again, until it was found by the ancient spirits of evil and given to Tara by the evil Mumm-Ra.
It now responds to her every commands, it also acts as a power booster which increases her magical abilities.
