Sto-vo-kor (or Sto'Vo'Kor) is, in Klingon mythology, the afterlife for the honored dead, where all true warriors go after they die to fight an eternal battle against great enemies. The halls of Sto-vo-kor were said to be guarded by Kahless the Unforgettable.
According to the tradition of ak'voh, whenever a warrior dies in battle, others stay with the body to keep away predators, allowing the spirit to leave the body and go to Sto-vo-Kor.
A Klingon can enter Sto-vo-kor by dying in battle or while performing a heroic deed. In addition, they may enter Sto-vo-kor by allowing themselves to be killed by another Klingon.
Alternatively, the relatives of the deceased can also perform such a deed in the name of the fallen to ensure their arrival in the halls.
