Early interstellar vessel launched in 2064 which was lost when it was carried out of the galaxy into the surrounding energy barrier, later detected via its recorder-marker log buoy. As a result of contact with the barrier one or more crew members showing high ESP'er capacity experienced mutations which turned them in god-like beings. The captain was forced to self-destruct his ship and all hands to prevent the affected crew from escaping into the populated galaxy.
