Why have you come here, child? Why have you interrupted my tireless musings?
—The Ghost of Lord Karros, to the Jedi Apostate
The Tomb of Karros was a Sith mausoleum built within walking distance of the Valley of the Dark Lords on Korriban as the final resting place of the Pureblood Sith Lord Karros, also known as the Lord of Lore and one of the great Sith philosophers.
Karros's followers, the Karrossi, erected the tomb for their beloved master, encasing his remains, lightsaber, and his holocron within its sacred precincts. The tomb remained Karros' home during his time spent as a Force ghost for several thousand years prior to the arrival of the Jedi Apostate, wherein he tirelessly reflected on the Force and its nature whilst fending off unworthy grave-robbers.
The tomb, cut into the side of a mountain, was nowhere as massive or imposing as its larger cousins down in the Valley of the Dark Lords. Regardless, it contained an extensive network of traps and tricks placed within by the Karrossi to guard their master's remains and legacy from tomb-robbers and the unworthy.
