|First appearance||Monstrous Compendium Volume One (1989)|
The orog first appeared in second edition in the Monstrous Compendium Volume One (1989), and appeared under the "orc" entry in the Monstrous Manual (1993). The orog of the Birthright setting appeared in the Birthright Campaign Setting (1995).
Orogs usually live among orcs; they are stronger, more intelligent, and more highly disciplined than typical orcs. They seem to have been inspired by the Uruk Hai from the Lord of the Rings.
Variants on the orog include the neo-orog and the ogrillion. The neo-orog is a specific orc-ogre crossbreed created by the Red Wizards of Thay to be used as elite soldiers. The ogrillion is the brutish, armor-skinned offspring of a female orc and a male ogre.
In the Forgotten Realms setting, Orogs were an orc tribe who became cut off from their mountain home after a great attack into the civilised world, they eventually found a way into the Underdark and hid from their Elven and human enemies. They remained in the Underdark for thousands of years, fighting deniziens of that terrible realm all the time. Eventually they became superior in strength and personality to normal mountain Orcs.
Both orogs and ogrillions appear in BioWare's Baldur's Gate PC games.
