The cathedral artifact was an artificial structure created approximately 500 million years prior to the 24th century. It spun on an interdimensional axis with some of its mass spinning into the dimensions of our universe in the Oort cloud of system GQ-12475 in the Gamma Quadrant. Some of its exterior was constructed from gold, platinum, other precious metals, and transuranic elements. In the 2370s, the artifact was known to local races the D'Naali and the Nyazen. The D'Naali called it Enti Leyza, which translated into Federation Standard as both cathedral and anathema.
