Vizsla Keep 09, also referred to as the Mandalorian asteroid outpost, was a supply outpost operated in the rings of Phelbos in the Bright Jewel system during the Clone Wars. Maul, leader of Death Watch, took Count Dooku and General Grievous to the outpost after capturing them during a battle on Ord Mantell. The Jedi Order and Galactic Republic tracked Maul and his Shadow Collective to the outpost, leading to an assault against Maul's forces.
During the Clone Wars, Death Watch commander Pre Vizsla built the keep as one of the many Mandalorian bases around the galaxy. Following Vizsla's death at the hands of former Sith Lord Maul, the Shadow Collective and Maul learned of it and took control of the keep. Following the battle on Ord Mantell, Maul went to the Keep. There, he contacted his old master, Darth Sidious and informed him of Count Dooku's and General Grievous's capture.
The Republic forces under Jedi Generals Obi-Wan Kenobi, Mace Windu, Aayla Secura, and Tiplee then attacked the outpost. There, they fought against Maul's forces, Dooku, and General Grievous until Dooku killed Tiplee. The Jedi were then knocked out by Rook Kast. Maul's forces were then forced to abandon it.
In 2 BBY, Maul had captured the Ghost's crew and brought them to the keep. Once there, Maul waited for Jedi Knight Kanan Jarrus and his apprentice Ezra Bridger to arrive with the Sith holocron. There, Maul had his droids take Ezra to the command center.
Maul then led Kanan to a airlock and pushed him into space. Kanan was able to use the Force to pull himself back to the Keep. He was then able to free his friends from Maul's droids. In the command center, Maul and Ezra then opened both the Sith holocron and Kanan's holocron. Together, they then combined the holocrons.
