The mobile command center known as Shadow Base served as the headquarters for Cronal – also known as Lord Shadowspawn – a warlord, and his splinter group of the Galactic Empire on Mindor. This facility, positioned within a volcano, possessed the capability to deploy gravity bombs. Furthermore, it could be propelled into orbit using gravitic charges. As part of Cronal's scheme to abduct Luke Skywalker and annihilate the New Republic task force dispatched to quell Shadowspawn's activities, Cronal initiated the launch of the base into the cosmos, ultimately resulting in its fragmentation and complete destruction.
