Aeon

Aeons communicate without language, first scanning beings for their thoughts and intentions and then projecting psychic flashes of a single concept in response. These flashes are usually a combination of visual and aural stimulation that communicate the aeon’s intent or understanding. An aeon’s envisaging functions as a nonverbal form of telepathy with a range of 100 feet, and it counts as a language for the purposes of telepathy and truespeech. Aeons can’t read the thoughts of creatures immune to mind-affecting effects.

Aeons can communicate telepathically with other aeons over vast distances. This ability works even across planes, albeit less effectively, allowing the communication of only vague impressions and feelings.
