Telepathic Cloud
Source
Interstellar Species pg. 26
Your nanites contain an advanced communications array that transmits your thoughts directly into the minds of those nearby, enabling you to telepathically communicate in environments and situations where a language would be impossible to visually or audibly articulate, such as using Lumos in bright sunlight or audible languages in Luminar’s dense, gaseous seas. You can communicate telepathically with any creatures within the area of your cloud array with whom you share a language.
