Darth Blackhole

After Axel Palpatine, the One Sith's defeat, and Nihl's conversion to the Gray Jedi, everyone assumed the Sith were no more. However, Darth Blackhole, a descendent of the feared Darth Malgus, was the last surviving Sith, along with his apprentice, Darth Howl. 
== Plans for Destruction==
The two planned to destroy the galaxy in 100 A.B.Y., however, the Sith's temple caved in, resulting in the deaths of their physcical form. However, Howl's spirit posseessed the spaceship, Ganner, while Blackhole's went into the replica armor of his ancestor Malgus. Blackhole decided they would wait for the next 200 years, before attacking. 
== Years in Wait ==
Over the next 200 years the two remaining Sith honed their power, and soon became more powerful then the feared Sheev Palpatine. They waited and honed their power, waiting to rule the galaxy.
