Hell (planet)
From Tardis Wiki, the free Doctor Who reference
Hell was the homeworld of the Helkans, who were enslaved by the Daleks to mine pockets of the highly toxic helkogen gas beneath the surface for the Death Wheel. The Seventh Doctor once arrived here by accident, having been attempting to travel to Maruthea. (COMIC: Nemesis of the Daleks, Emperor of the Daleks!)
