Darth Sidious's secret facility

Darth Sidious's secret facility was an outpost maintained by the Sith Lord Darth Sidious in a former mining complex located near a lava lake on the southern hemisphere of the planet Mustafar. During the Clone Wars, the bounty hunter Cad Bane delivered kidnapped Force-sensitive children there, where the Sith Lord planned to have them converted into dark side spies. The facility was destroyed by Sidious and his nanny droids when it was discovered by Anakin Skywalker and Ahsoka Tano, two Jedi on a mission to rescue the children.
