Dulaine
Dulaine was an inhabited planet. It was the homeworld of the Dulainians, a spacefaring humanoid species, and of an ancient sentient volcano named Morgo. The planetary environment included oceans and tropical islands lush with brightly colored flora.

Because Dulaine's thermosphere contained charged ions that blocked transporters, the Dulainians constructed a system of orbital lifts for transportation to and from the surface.

In 2382, the  arrived at Dulaine to repair a malfunctioning orbital lift, while hosting the stranded travelers in the interim. An away team consisting of Commander Jack Ransom, Lieutenant Commander Andy Billups, and Ensigns Beckett Mariner and Sam Rutherford was dispatched to the lift on the shuttlecraft Death Valley. Wanting to prove that Beckett would disobey his orders, Ransom assigned her and himself to the repairs and Billups and Rutherford to liaising with the Dulainians, despite the mismatch with their respective aptitudes. This led to Billups and Rutherford inadvertently causing an incident in which they were almost sacrificed to Morgo. ()
