The Ni'Korish were a group of anti-Jedi individuals originating from the Hapan Hapan Royal Navy, brought together by the ideology of the Queen Mother named Ni'Korish. Typically, they were comprised of ex-Hapan Navy members turned pirates, identifiable by their red attire. Subsequently, certain members, along with some unconnected Hapan individuals, became affiliated with the Peace Brigade.
During the time of the Yuuzhan Vong War, this group was led by Ta'a Chume, and the Ni'Korish made numerous attempts to assassinate Teneniel Djo. Every plot was unsuccessful, with the exception of the final one, leading to Djo's death by poisoning in 27 ABY.
Afterward, Ta'a Chume determined that the Ni'Korish had served its purpose, and she betrayed them. Every identified Ni'Korish member was captured and executed as punishment for the murder of Teneniel Djo.
