Star Trek: 10 Crazy Facts About Klingons
7. The Living Literally Fight For The Dead
When a Klingon dies in honorable combat, their spirit is said to pass on to Sto'Vo'Kor. It's their version of Heaven except it's filled with an eternity of feasting, Blood Wine and battle. It's kind of awesome when you think about it. Klingons who follows the Way of the Warrior are welcomed to Sto'Vo'Kor by Kahless, the first Klingon Emperor who united their houses and know serves as a messianic figure in their culture.
But what happens to those who follow the Way of the Warrior and have not earned their way into Sto'Vo'Kor? In cases like that, the living have an option to help the dead.
To help a loved one make the passage, their friends and family can complete an almost impossible epic quest. If the mission is successful, their deceased loved one will gain entrance to Sto'Vo'Kor. Worf, General Martok and group from Deep Space Nine completed such a task in honor of Jadzia Dax after she lost her life at the hands of Gul Dukat.
The journey to Sto'Vo'Kor does not end with death.
