Takara's stronghold was a fortress built on a planet and was Takara's personal base of operations.
Built directly out of a cliff side to the south and surrounded by water to the north, the building was very difficult to enter. Inside, there were many rooms of varying design, including a droid torture facility, a private skiff dock, and, most notably, a rancor pit.
It also had an extensive dungeon complex, containing fifteen cells, guarded by a pair of Gamorreans. However, the back wall of one of the cells was collapsed, allowing anyone with access to the cell to escape into the sewer system beyond. Such an endeavor would likely have been useless, as the only real exit led directly to the rancor pit.
In 10 ABY Mara Jade was imprisoned in Takara's stronghold after falling into a trap lain in Katraasii Spaceport by Abron Mar. After fighting her way clear of the dungeons with her bare hands, she was able to kill Takara's rancor, steal a valuable GCT devise, and successfully escape to return to the New Republic.
Takara's stronghold is the setting of an entire level in Star Wars: Jedi Knight: Mysteries of the Sith.
