Benev Selec
Benev Selec, also known as Drema IV, was the inhabited fourth planet of the Selcundi Drema system. This system was located in the Selcundi Drema sector and was the homeworld of the Dremans, a humanoid species, whose civilization was classified by the Federation, in 2365, as pre-warp.

In that year, the  became the first manned Starfleet starship to survey the planet. An analysis by the Planetary Geosciences Division aboard the ship into the cause of the planet's geologically unstable state was discovered to be the result of the largest deposit of dilithium ore ever recorded. The ore was laid in an unusual pattern, with the crystals forming perfectly aligned lattices. This action was turning the ore into a generator strata which produced a piezoelectric effect. In plain English, "The crystals take the natural radiant heat of the planet, focus it, and turn it into mechanical energy which increases tectonic stresses that tear the planet apart. And then the crystals break down, which is why we found all these traces of Illium-629."

During the mission, Lieutenant Commander Data detected a low-level RF signal sent by a Dreman girl, Sarjenka. She asked if there was "anyone out there", prompting Data to respond. Data informed Captain Picard of his contact with Sarjenka after he learned that Drema IV was on the verge of self-destruction. Because Data's actions violated the Prime Directive, Picard initially ordered Data to sever all contact with the surface. However, when he heard Sarjenka's voice, telling Data she was afraid and asking for his help, Picard decided that they must act, chosing to catagorize Sarjenka's plea as a distress call.

The survey team, headed by acting Ensign Wesley Crusher, suggested that harmonic vibrations emitted by class-1 probes fitted with harmonic resonators fired into the planet would shatter the planet's dilithium lattices and thus alleviate the tectonic stresses tearing the planet apart. The plan was a success and the planet was saved from destruction. ()

Background information 
The planet's name – Benev Selec – was seen in an okudagram in Data's quarters aboard the Enterprise-D. According to the , Benev Selec was the name of Drema IV's system.

"DRAY-mah" was the pronunciation for Drema according to the  pronunciation guide; however, according to StarTrek.com, the pronunciation was "DRAY-muh". 

The planet model first used here for Benev Selec was later used for the Starbase 515 planet, () Rutia IV, () and Beta Agni II. ()

Apocrypha 
In the Star Trek: SCE eBook , a mining accident occurs on Drema IV, and it is noted that the planet has become a Federation protectorate.
