Telepathic humanoids from deep space. Recent contacts with a strong interest in joining the Federation. The Cairn have no concept of spoken language and have almost no vocal ability. Cairn telepathy is different from most telepathy. Most races telepathically transmit words and sounds, the Cairn however transmit pure thoughts and images. This is far more efficient but can only be practiced by Cairn. Since first contact with the Federation, the Cairn have struggled to learn common telepathy, develop speech enhancers, and learn spoken language. The Cairn appear to be standard humanoids with a textured bony enlargement just over the ears. Cairn technology is limited to rudimentary interstellar spaceflight.
