Simply an example of race flavor. A typically civil breed of sphinx who were originally guards and watchman for humanoid temples. When the number of elmpheens grew in times of plenty, they took to other jobs in the cities and lands they inhabited. Slowly, acceptance grew and they integrated into civilized societies, making their way amongst humanoid cultures as contributing members. They lack the wild, unrefined bestial nature of their sphinx cousins. Perhaps they've lived with humans too long, but they are rarely found in the wilds.
