|Quest||Repairing the Orrery|
|Location||Imperial Orrery, Arcane University|
|Released||April 17, 2006|
The Orrery is an official add-on for Oblivion, adding a new quest to repair the Arcane University's Orrery. Restoring the Orrery grants you a greater power that will fortify one attribute while draining another. The particular power that you receive is based on the phases of the moons, Masser and Secunda.
- Harness the power of the stars. Rebuild the defiled Orrery and unlock the secrets of this Mages Guild Inner Sanctum. —Former Official Summary
- The Orrery Pack allows you to help the Mages Guild of Cyrodiil repair the Imperial Orrery, an ancient dwarven machine with mystical properties. Bandits have stolen a shipment of parts destined for the Arcane University; if you can return them, the Orrery will function once more. —Current Official Summary
- Items — 4 new miscellaneous items and 2 letters are included with the add-on.
- Magic — 8 new greater powers are available once the Orrery is repaired.
- Quest — Assist Bothiel in repairing the Imperial Orrery.
This letter was originally displayed on the official obliviondownloads.com website, which has since become unavailable. The text serves to provide background and context for the events of the add-on.
- The door to the Imperial Orrery is present even without this add-on. If you use console commands to break into the Orrery without installing the add-on, the interior is simply an empty dome structure, scaled to be much larger than normal.
