The Children of the Lost Ones (called Outsiders by the Tholian Assembly) were a splinter group of Tholian society who retained the racial memory of a sectarian war fought in the Veletus system millennia prior to the 23rd century. This battle resulted in the release of the high energy plasma that constituted the life energy of billions of Tholians. This plasma later coalesced to form what became known as the Ifukube Veil, though the distinct energy signatures of individual Tholians continued to exist within the phenomenon.
