Orogs were descended from black orcs from the Scara Mountains. Frightened by an encounter with the cannibalistic Jerren, the orcs fled. They sought refuge in a narrow cave at the end of a valley which, unbeknownst to them, led to the World Cavern. They became lost but felt safe in the knowledge that they would not be followed by their enemies, delving further underground whenever they could. Eventually they came across a veritable jungle of luminous fungi and decided to settle there, calling it "Kulamak Votar" or Glowhome. They bred in great numbers and expanded into many surrounding caverns like a virulent plague. They subjugated the creatures already living there and eventually split into a dozen different tribes, discovering rich veins of metal and ore.
After generations of exposure to the World Cavern energies orogs have gone through many changes, barely resembling the original black orcs. Orogs stand around 8 feet tall for both males and females. They are very thin, with almost elf-like features with ashen black features that turn a sickly pale yellow if exposed to prolonged sunlight. Orogs possess an infernal intelligence that outclasses any other orc, save for the scro whom they venerate as all other orcs do.
One notable orog was Bolg the Bloody.
