PM-1203 was a planetoid located in the galaxy's Core Worlds. It was created from the remains of the planet Anaxes after it was obliterated in a cataclysmic event following the Clone Wars, though Fort Anaxes, a Galactic Republic military base, miraculously survived the world's destruction on the newly-created planetoid's surface. The facility became a fuel depot and meeting place for those who required privacy in their dealings, though, unbeknownst to its visitors, Fort Anaxes had also become home to a colony of vicious fyrnocks nested on PM-1203.
