In the Exile/Avernum series of adventure games, the Nephilim are a species of feline humanoids. Though native to the surface world, they were long ago banished to Exile by the Empire. They live in tribes, often led by shamans or by members of the stronger Nepharim breed. While a large number of Nephilim remain "wild" and prey upon the human Exile population through banditry, many have become "civilized" and allied to the Exiles.

Nephilim tend to be very dexterous, and favor the use of missile weapons in combat.
