The second official plugin for Oblivion is out now for PC users. It’s called The Orrery and its description is:

Harness the power of the stars. Rebuild the defiled Orrery and unlock the secrets of this Mages Guild Inner Sanctum.

It weighs in at 18 mb and costs $1.89. It’s about a 15 minute quest (spoiler type screen shot) that gets you access to the Orrery in the Mages Guild. This can be used by melee guys not yet a full member of the Mages Guild.

Content wise it’s more than the Horse Armor plugin. The question is that is this enough to justify the 1.89 price tag? It depends on your point of view. A less scrupulous sort of person would goto illegal means to acquire this plugin.
