Plea for the Dead

From Memory Alpha, the free Star Trek reference

The Plea for the Dead is a Klingon prayer said at mid-day to honor the sacrifices of their ancestors. Accordingly, the dead can not rest in Sto-Vo-Kor if the living do not honor their memory.

As a child, B'Elanna Torres said the prayer for her grandmother, L'Naan. (VOY: "Prophecy")
