A being who described himself as a Traveler, but whose real name he claimed was unpronounceable by Humans, was a humanoid from a mysterious species, encountered by Starfleet during the 2360s. Reported to be from Tau Alpha C, he himself claimed to be a traveler on a journey to experience "your reality". Eventually, he took Wesley Crusher with him to help the young man in the development of his own extraordinary abilities.
