A conflict between Atlec and Straleb nearly broke out in 2365 when the Straleb Jewel of Thesia was thought to have been stolen by Thadiun Okona, who was also accused of impregnating Yanar, the daughter of the leader of Atlec, Debin.
Following a confrontation involving the Federation starship USS Enterprise-D, an Atlec vessel and a Straleb security vessel, it was revealed that the jewel, which was in Okona's possession, was destined for Yanar, from Benzan, the heir of the jewel. (TNG: "The Outrageous Okona")

This planet's quadrant of origin is inferred based on the position of its star system as seen in the star charts appearing in the Star Trek: Discovery episode "Die Trying" and in the Star Trek: Picard episode "Maps and Legends".
The planet's name was spelled as "Altec" in the Star Trek Encyclopedia (3rd ed., p. 9) and in the Star Trek: Star Charts ("United Federation of Planets I"); however, it was spelled as "Atlec" in the script  and at StarTrek.com.
