P4X-347 is a Goa'uld world which has been abandoned for several hundred years. Enormous sphinx-like statues line a beach near a deserted pleasure palace that contains writings in an obscure Goa'uld dialect. Within the palace, a pedestal projects a strangely addictive light-matrix hologram onto the ceiling. The sole inhabitant of the planet was Loran, a young man whose parents had been explorers who had succumbed to the addictive effects of the light and died. Loran had lived alone since his parents' death, and he returned to Earth with SG-1, leaving the planet abandoned once again.
