Suns! Moons! Stars! Yes!...The angle of eternity!Aughra, 
The Orrery was a mechanical contraption located in Aughra's observatory. It consisted of metal representations of heavenly bodies of Thra's solar system and their respective positions and movements. Aughra used it to make predictions about future celestial occurrences, especially the time of the Great Conjunction.
It was built during the early Age of Harmony by the urSkeks, in gratitude for Aughra teaching them the nature of Thra and its inhabitants. TekTih and ShodYod in particular were instrumental in its construction. The orrery was short circuited and destroyed by the Garthim during the late Age of Division whilst seeking to capture Jen.
