Lenkit Casten was a Bajoran woman.
In 2377, Lenkit was among the scientists killed on Endalla when the waves from an Ascendant isolytic subspace weapon hit the installations on the moon. In 2385, Galdus Mon tried to contact Lenkit, seemingly not knowing of the tragedy on Endalla that had occurred and that Lenkit was dead. A few years before her death, Lenkit had purchased a Lorillian art sculpture from Mon. (DS9 novel: Sacraments of Fire)
