Sernpidal essentially belonged to the Outer Rim, but it was considered more akin to Wild Space.[1] The surface of the planet was dusty, and subterranean agri-farms were watered by aquifers. Damp ravines were occupied by slow, tough, tentacular creatures which comprised the planet's flora and fauna both.[1]
During the Jedi Civil War, the planet was under the control of the Sith Empire, and served as a major Sith naval base in possession of sensitive military codes and equipment. Later on at the beginning of the Great Galactic War the Sernpidal government was replaced by a puppet government that sided with the Sith in the war.
In 365 BBY, it was settled by the Sernpidalians fleeing the supernova of the planet Hettitite, who reached an 8 million-strong population, the greatest in the sector.[1]
The planet's large population caused it to be an effective target in 25 ABY, when the Praetorite Vong placed a dovin basal on the surface of the planet outside Sernpidal City, causing the smallest of its two moons, Dobido, to be pulled into the planet in a spiraling orbit. Han Solo, Chewbacca, and Anakin Solo made an attempt to evacuate as many people as possible, but Chewbacca was lost in the process when Dobido hit the planet. A chunk of the hemisphere was almost split, stripping the atmosphere. The Vong used a colony of snail-like builders on the broken fragments to digest and regrow them into a shipwomb.
Later on, Rogue Squadron led a successful assault on the planet, thinking that the system held a superweapon, and destroyed all that remained of the planet.[1]
