In 2368, Geordi La Forge and Data were researching the records of planets visited by an Ullian delegation of telepathic historians. One of the planets visited was Melina II. La Forge and Data were looking for a correlation between unexplained cases of comas or medical cases diagnosed as Iresine Syndrome and the mission logs of the Ullians. This was after several crewmembers aboard their ship, the USS Enterprise-D, became comatose. The Enterprise-D was transporting the delegation to Kaldra IV, and a member of the delegation was suspected as being responsible for the coma-like state of the crewmembers. (TNG: "Violations" )
