In 2370, members of this species attempted to telepathically communicate with the crew of the Federation starship USS Raman, but the process accidentally caused the deaths of all seven crew members. The beings were then trapped aboard the Raman in the planet's upper atmosphere, where they could not long survive.
When the USS Enterprise-D arrived to investigate the fate of the Raman, Lieutenant Commander Geordi La Forge encountered one of the beings through the interface probe. Reading La Forge's mind, the being masqueraded as his missing mother Silva La Forge to convince him to bring the Raman deeper into the atmosphere, so that it and the others of its kind could escape. It eventually revealed its true nature to La Forge, who helped to release them from the ship. (TNG: "Interface")
