Void Branch
Void Branch is the sword of a Xixian princess, recovered after her defeat in the siege of Velthryn in 2730VF. After being retrieved by a Thornguard captain who helped force the princess into retreat, the Void Branch was passed down through his family for several generations, before eventually being sold to cover the family’s gambling debts. From there, it passed into the hands of a master thief, who was not masterful enough to steal from Lord Kyestri's vault. The weapon nullifies all nearby sorcery and cleaves through both sorcerous and physical defenses with ease[1].
Appearance
Void Branch is intensely black and has a broad curved blade. It is unknown whether its coloring is a result of the material of the blade or a sorcerous effect. It emits a visible aura of sorcery[1].
History
World Cutter was in Kyestri's vault up until the events at the end of Defying Destiny, when it was looted and put into the Jaden Box[2].
When the Jaden Box is opened in On the Shoulders of Titans, it is not mentioned, most likely given to Taelien later, as it was previously arranged that he would get "all the swords"[2][3].
