Two hundred nine thousand, four hundred sixty-two years ago,
while inhabiting their seven planets somewhere in Universe
6, the Boxnards developed a form of teleportation. This event
terrified the Psychlos.
It is thought that the Boxnards tried to put teleportation
to military use, but the Psychlos
got there first and completely obliterated them, along with
all of their planets and anyone associated with them. The
Boxnards were effectively driven to extinction.
