Dramia II was the second planet in the Dramian system, and was colonized by the Dramians sometime prior to the 2250s.
In 2251, Dramia II was visited by Leonard McCoy, who was the head of a massive inoculation program on the planet. While on Dramia II, McCoy saved a Dramian colonist, named Kol-Tai, from a strain of the Saurian virus. Shortly after McCoy departed, the colony was hit by an auroral plague that killed most all of the planet's colonists. McCoy was blamed for their deaths.
Nineteen years later, McCoy was arrested and charged for the mass murder of Dramia II's inhabitants. He later found an antidote for the plague and was cleared of all charges. (TAS: "Albatross")
According to the Star Trek: Star Charts ("United Federation of Planets I"), Dramia II was listed as a member planet of the Federation in 2378.
