An orrery is a mechanical device that illustrates the relative positions and motions of the moons or planes in an Eberron -centric model. [1] [2] [3]
Description
An observatory orrery such as the Orrery of Vortuum comprises a tower with multiple sections and levels that rotate slowly around the central axis while spheres representing the moons and planes revolve around it on rings. The whole device is powered by magic and established inside an observatory, [1] [2] [3] [4] such as a planar observatory [5] or Siberys observatory . [6] A dragon-built orrery is intricate but necessarily big enough to be manipulated by dragon claws. [6] [7] Multiple orreries may be installed in one observatory. [5]
Usage
Orreries are employed by astronomers and sages to track the proximity of the planes to Eberron, and thereby ascertain when they are coterminous, and have an influence on the world. [8]
Notable Orreries
Great dragon -built orreries are located in Argonnessen , [1] such as the Orrery of Vortuum . [3] The silver dragon Zenobaal has an orrery within his cloud palace, [9] while the black dragon Marrowdrax created one as part of a living tree. [2]
