Curse of the Crimson Throne
The magic sword that slew Kazavon. Presumed to be still at Scarwall where Mandraivus nearly certainly fell. The actually location is unknown, although it is doubtful that a servant of darkness could transport let along wield the holy blade of Iomedea.
Having braved the depths of Scarwall, the might relic has been removed and has now been taken to Korvosa, hopefully to deliver swift justice to Queen Iliosa.
