Background: Mustafar was a small volcanic planet
located in the Mustafar system, situated between two
gas giants in the Outer Rim Territories that was aligned
with the Confederacy of Independent Systems during
the Clone Wars and later taken over by the Galactic
Empire after the Techno Union was nationalized at the
conclusion of the conflict. Mustafar had an array of
valuable minerals which were mined by the Techno
Union, and was the headquarters of the infamous Black
Sun during the Clone Wars.
The planet's native Mustafarian species lived in
underground caves created by lava fleas as they ate
through the planet's crust, and made their armor from
the heat-resistant shells of the creatures. Only
venturing up to the surface in order to collect valuable
minerals from the lava flows, the short and strong
southern Mustafarian subspecies carried out the heavy
labor involved, while the tall and slender northern
Mustafarian subspecies acted as guards and expert lava
flea riders. Due to the planet-wide lava surface, all
buildings were held up by gravity supports. Its capital
city was Fralideja.
During the age of the Empire, Mustafar became a
fortified Imperial world as it housed the personal castle
of Darth Vader.
