Scepter of Orr
The Scepter of Orr is an ancient artifact originating from Orr. Along with the now-destroyed Staff of the Mists, the Scepter of Orr was given to the humans of Tyria as a gift from the Gods of Tyria. The exact powers of the staff are still not fully known (though it has been used in the past to control titans), but it is known that its sister, the Staff of the Mists, had the power to bend the fabric of the universe to the will of its user, so it can be assumed that its powers are many.
After Battle of Lion's Arch, a necromancer named Livia found the Scepter, which had been hidden by Glint. It is not known why she sought it, but it was said that Livia sought a 'weapon of power' to bring an ultimate end to the civil strife between the White Mantle and the Shining Blade in her homeland of Kryta, and that she would be prepared to bear any sacrifice - not limited to herself, but also those around her, in order to achieve this end. However, when Livia found the Scepter of Orr, the War in Kryta was already over and the White Mantle were defeated.
How Livia used the Scepter and what ultimately happened to it are unknown, but it is known that she wielded its powers for a time.
