Ne'tu is described in Earth mythology as the underworld Sokar commanded, believed to be inhabited by "serpents and the damned." It is a literal hell, a place of fire and torment from which there is no return. In fact, Ne'tu was a moon controlled by the rogue Goa'uld Sokar, who used it as a prison for his captured enemies.

The surface was scarred with meteorite hits. Volcanic gashes covered much of the surface. Sokar himself exposed the moon's molten core, terraforming the world to fit the myth of hell. Consequently, there was a high sulfur content in the air, forcing temperatures to escalate to unusually hot levels. Ne'tu orbited Sokar's home base, Delmak, until its destruction.
