Ophir is mostly rolling plains, with forested regions throughout. In the east, it turns mountainous, merging into the rocky Nemedian-Corinthian border at its eastern end. Ophir is slightly rainy, with western storms pouring along the western edge of the mountains. There is little snow, except on the highest peaks, but the winters can become bitterly cold, with sudden drops below freezing.
Ophir abounds in gold, silver and gems. Some of the finest jewelers in the West reside in Ophir (where their raw materials are in the most abundance).
Ophir has a Hyborian culture, very similar to that of Aquilonia. The most striking difference is the presence of wealth among the populace. Ophir's military wears gilded armor, and almost every bourgeois person has a sizable quantity of gold jewelry and gemstones.
This wealth, and the associated standard of living in Ophir, has given the Ophireans a reputation for generosity unsurpassed among the Hyborian nations. It is said that no one goes hungry in Ophir, and that no one sleeps in the cold. Though this is a slight exaggeration, it is true that the Ophireans are free with their belongings, and their "charitable contributions" to other nations are unsurpassed.
The Ophireans are devout Mitra worshippers, although this belief is tempered with more religious tolerance than is seen in Aquilonia. Nature worship has a following here, but it is limited to the more remote villages and towns.
