Omicron Theta was a Federation colony that was destroyed by the Crystalline Entity in 2336. The only known survivors were Data and Lore, the creations of Doctor Noonien Soong. Data was found by a passing Federation starship. Lore remained dismantled until the USS Enterprise-D found and assembled him. Lore, it was later discovered, had called the Crystalline Entity to the colony. Also, it was later discovered that Soong and his wife had escaped the destruction of the colony. This was discovered when Dr. Soong "called" Data so that Dr. Soong could give Data an emotion chip. (TNG episode: "Datalore")
