The Endalla falsework was a mysterious structure found below the surface of Endalla, one of the moons of Bajor.
Extremist elements of the Ohalavaru believed Endalla was the location of proof that would confirm their belief that the Prophets were not gods. After detonating explosives on Endalla in 2380, and after testing Starfleet's defenses around Endalla in September 2385, the Ohalavaru discovered a structure, which Travil Asand called a falsework, in December that year. Travil described the falsework as once holding what the Prophets had used to construct the Bajoran wormhole. (DS9 novel: Sacraments of Fire)
