From The Stargate Omnipedia
Planet originally under the control of Baal
Baal's presence was replaced by his emissary, Lord Mot, who continued to sap the naquadah resources of the world for himself. SG-1 arrived to the world and was eventually able to defeat Lord Mot with help from the locals.
A full moon heralded Mot's presence on the planet. He would arrive to torture the population for the scarce naquadah deposits.
P4S-237 is rugged in terrain. Pipes extrude from its service, possibly connecting to a naquadah refinery below.
HOME TO - Ellori's people
FIRST APPEARED - Prophecy
Prophecy - SG-1's presence fulfills the population's prophecy that, one day, a great presence will arrive and free the people from Goa'uld oppression.
