Space Station Trenchant

Trenchant Space Station was located somewhere in the Outer Rim. It was the scene of the battle between Asajj Ventress, Durge and General Grievous. Grievous' victory ensured that it was he who became Supreme Commander of the Droid Armies of the CIS.

The Ship/Space Station
The space station itself likely belonged to a very wealthy person. It contained many artifacts and dead animals and species as well as living ones. Pteradactyls, flying multi-eyed organisms, creatures from Nelvaan, bugs, apes, and sea lifeforms were kept in bacta tanks or just as relics. The space station had many other relics as well. There were many vibro-blades and knives. There were also collections of lightsabers and Jedi robes. Suits of armor, antique vases, ancient speeders, skeletons, statues of Count Dooku, droids, and globes were present as well. This could have belonged to several people. It most likely belongs to Count Dooku, since he picked the area for the fight. It could have also been a gift to Grievous. The ship may have belonged to someone who loved the Separatists. This person most likely knew how to fight Jedi, or where to obtain relic lightsabers.
