She once said "What remains after death is but a shell... a sign that the pagh has begun its final journey to the Prophets." In 2372, Dukat quoted her to Kira Nerys to convince her not to view a collection of remains which included Bajorans and Cardassians, as Bajorans were more concerned with souls than bodies, unlike Cardassians, who considered allowing non-Cardassians to view their bodies as a form of dishonor to the dead. (DS9: "Indiscretion")
This character was only mentioned in dialogue.
Meressa appears in the Star Trek: Terok Nor novel Day of the Vipers. She was depicted as the serving kai at the time of the official first contact between her people and the Cardassians in 2318. She died from the effects of a degenerative neurological disease known as Yerrin syndrome in 2325, three years before the official start of the Occupation of Bajor. The novel included the quotation given above, indicating that Dukat gave Kira Nerys a direct quotation, as in the novel Dukat was present at a reception Kai Meressa attended.
