In the script of "Dagger of the Mind", Tantalus V was described as "a planet almost featureless except for the ravages caused by its extreme climateric." Also, the planet's landscape was described as "eerie".
For the remastered edition of "Dagger of the Mind", Tantalus V was depicted with newly created computer-generated shots which added the planet's ring system. The digital footage also completely replaced the matte painting representing the planet's surface. The footage of the planet was co-created by Max Gabl, who commented, "I only did the planet, the rings were added later. I remember putting them into the surface painting though."
