Rogue's Gallery

Rogues Gallery was a short story in Clone Wars Adventures: Volume 3.

Plot
In the beginning of the story, Asajj Ventress and Durge are searching a large spacecraft because Darth Tyranus senses somebody aboard the vessel. Both of them enter a rogue's gallery within the ship (hence the name of the story), and say that they are approaching each other, and also say that if anybody is in the gallery, they have blocked off all exits.

Durge is attacked by the mysterious enemy, who turns out to be General Grevious. After a lengthy battle between the two factions, Grevious defeats Ventress and Durge, and takes their bodies back to Tyranus, who says that Grevious has passed his test, and orders the Kalee to put them in bacta tanks.
