The final resting place of the deceased King Hakagram Graush was the Tomb of Hakagram Graush, a Sith mausoleum situated on Korriban. This tomb was constructed circa 6900 BBY. Darth Plagueis ventured into Graush's tomb many millennia afterward, with the expectation of confronting a Sith spirit. It seems that Plagueis found no spectral presence within the tomb, much to his dismay.
