The Oracle Engine is an arcane device located beneath the Observatory in the Dreaming City. It functions as a means of communication between different planes of reality, as well as transportation between planes.
At some point after the construction of the Dreaming City, three Techeuns became possessed by an unknown group of entities. These beings used the Techeuns to address Mara Sov, who identified them as "the Ancients". During their conversation, the body of one of the Techeuns, Kelda Wadj, collapsed into a singularity. This singularity was later used to construct the Oracle Engine.
